The Bible calls for wholehearted commitment. God said of Caleb that he "hath followed me fully" (Numbers 14:24), and Israel promised, "The LORD our God will we serve, and his voice will we obey" (Joshua 24:24). Commitment also means keeping your word: "he shall not break his word" (Numbers 30:2). Best of all, God commits Himself to us: "I will not turn away from them, to do them good" (Jeremiah 32:40).
We live in a culture of easy exits. Subscriptions can be canceled with one click, and it is tempting to treat relationships, churches, jobs and even faith the same way. The Bible calls us to something deeper. It praises people who follow God fully, who count the cost and keep going, and who keep their promises even when it hurts. Commitment is not stubbornness for its own sake; it is love that stays. These twelve King James verses cover commitment to God, the cost of following Jesus, and the vows we make to God and to each other, ending with God's unbreakable commitment to us. For related themes, see Bible verses about being faithful, loyalty and consistency.
Wholehearted commitment to God
1. Numbers 14:24
"But my servant Caleb, because he had another spirit with him, and hath followed me fully, him will I bring into the land whereinto he went; and his seed shall possess it."
When twelve spies explored the promised land, ten came back afraid. Caleb and Joshua trusted God. God said Caleb had another spirit with him, and hath followed me fully. Forty-five years later, Caleb could still say, "I am this day fourscore and five years old" (Joshua 14:10), and he asked for the hardest hill country to conquer. Wholehearted commitment does not fade with age. It can grow stronger.
2. Joshua 24:24
"And the people said unto Joshua, The LORD our God will we serve, and his voice will we obey."
At the end of his life, Joshua gathered Israel at Shechem and asked them to choose whom they would serve. Three times they promised, and the third time they said, The LORD our God will we serve, and his voice will we obey. Joshua wrote it down and set up a stone as a witness (Joshua 24:26-27). Public commitments, like baptism, marriage vows or church membership, help us remember what we promised when feelings fade.
3. 2 Kings 18:6
"For he clave to the LORD, and departed not from following him, but kept his commandments, which the LORD commanded Moses."
King Hezekiah clave to the LORD, and departed not from following him. To cleave is to cling or hold fast, the same word used of a husband cleaving to his wife (Genesis 2:24). Hezekiah's commitment was tested by an invading army and a life-threatening illness, and he kept turning to God. Commitment is not a single decision; it is choosing to hold on again every day, especially on the hard ones.
4. Psalms 119:112
"I have inclined mine heart to perform thy statutes alway, even unto the end."
I have inclined mine heart to perform thy statutes alway, even unto the end. To incline is to lean or bend. The psalmist chose the direction of his heart. Commitment often starts as a decision before it becomes a feeling. You can incline your heart toward God by small, repeated choices: opening the Bible, praying, showing up to worship, obeying in small things. Over time, the heart follows where it has been bent.
Counting the cost of following Jesus
5. Matthew 13:44
"Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field."
A man found treasure hidden in a field, and for joy thereof goeth and selleth all that he hath, and buyeth that field. Notice the motive: joy. He did not sell everything grudgingly; he gladly gave up lesser things for something far better. Commitment to Jesus is costly, but it is not a sad sacrifice. It is the happiest trade anyone can make, giving up what we cannot keep to gain what we cannot lose.
6. Luke 5:28
"And he left all, rose up, and followed him."
Levi, also called Matthew, was a tax collector sitting at his booth when Jesus said, Follow me (Luke 5:27). And he left all, rose up, and followed him. For a tax collector, leaving was a point of no return; fishermen could go back to fishing, but Levi could not easily get his job back. Real commitment sometimes means closing doors behind us. Then Levi threw a party so his friends could meet Jesus (Luke 5:29).
7. Luke 9:59-60
"And he said unto another, Follow me. But he said, Lord, suffer me first to go and bury my father. Jesus said unto him, Let the dead bury their dead: but go thou and preach the kingdom of God."
When a man asked to first bury his father, Jesus answered, Let the dead bury their dead: but go thou and preach the kingdom of God. It sounds harsh, but many scholars think the man meant he would follow later, after his father eventually died. Jesus was not against caring for family; elsewhere He condemned neglecting parents (Mark 7:10-13). He was exposing a commitment that always had a reason to wait.
8. Acts 21:13
"Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus."
Friends begged Paul not to go to Jerusalem, where prison waited. He answered, I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus. Paul was not reckless; he was settled. When the cost of commitment becomes clear, people who love us may try to talk us out of it. Paul's friends finally said, "The will of the Lord be done" (Acts 21:14).
Keeping your word, and God keeping His
9. Numbers 30:2
"If a man vow a vow unto the LORD, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth."
Under the law, a vow to the LORD was binding: he shall not break his word, he shall do according to all that proceedeth out of his mouth. God takes our words seriously because He keeps His own. In a culture of casual promises, being someone whose yes means yes is a powerful witness. Before making a commitment, count the cost; after making it, keep it.
10. Ecclesiastes 5:4
"When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed."
When thou vowest a vow unto God, defer not to pay it. Solomon warns against making promises to God in a moment of emotion and then forgetting them. The next verse is even more direct: "Better is it that thou shouldest not vow, than that thou shouldest vow and not pay" (Ecclesiastes 5:5). If you have made promises to God you have not kept, the answer is not shame but honest repentance and a fresh start.
11. Psalms 116:14
"I will pay my vows unto the LORD now in the presence of all his people."
I will pay my vows unto the LORD now in the presence of all his people. The psalmist had been rescued from death (Psalm 116:8), and he kept the promises he made when he was in trouble. He did it publicly, in the presence of all his people. Commitment grows stronger in community. Telling trusted friends about your commitments, in marriage, in recovery, in faith, invites them to help you keep them.
12. Jeremiah 32:40
"And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me."
This is the best news about commitment: God's commitment to us is stronger than ours to Him. He promises an everlasting covenant, that I will not turn away from them, to do them good. He even promises to put reverence in our hearts so we will not turn away from Him. When your commitment wavers, rest in His. The God who began a good work in you will complete it (Philippians 1:6).
A short prayer
Lord, You have committed Yourself to me with an everlasting covenant, and You never turn away. Make my heart like Caleb's, following You fully. Help me count the cost of following Jesus and choose You with joy. Teach me to keep my word to You and to the people I love, even when it is hard. Where I have broken promises, forgive me and give me a fresh start. Incline my heart to You every day, even unto the end. In Jesus' name, Amen.

Frequently asked questions
What does the Bible say about commitment to God?
Scripture calls for wholehearted commitment: "thou shalt love the Lord thy God with all thy heart" (Mark 12:30). Caleb followed God fully (Numbers 14:24), Hezekiah clung to the LORD (2 Kings 18:6), and Jesus calls disciples to count the cost (Luke 14:28). Psalm 37:5 is another favorite: "Commit thy way unto the LORD; trust also in him" (Psalm 37:5).
What does the Bible say about commitment in marriage?
Marriage is a covenant, not a contract. From the beginning, a man "shall cleave unto his wife: and they shall be one flesh" (Genesis 2:24). God models covenant faithfulness Himself: "I will even betroth thee unto me in faithfulness" (Hosea 2:20). Keeping vows in marriage reflects God's own commitment to His people. See Bible verses about love and marriage.
How can I stay committed when I feel like giving up?
Remember why you started, and lean on God's commitment to you rather than your own strength. Keep small daily habits, tell trusted friends where you are struggling, and take the next faithful step. Paul wrote, "let us not be weary in well doing: for in due season we shall reap, if we faint not" (Galatians 6:9). See Bible verses about consistency and never giving up.
What is a good Bible verse about keeping your word?
Numbers 30:2 and Ecclesiastes 5:4 on this page are clear about vows. Jesus said, "let your communication be, Yea, yea; Nay, nay" (Matthew 5:37), meaning your simple word should be trustworthy. Psalm 15 describes the person who "sweareth to his own hurt, and changeth not" (Psalm 15:4), someone who keeps a promise even when it costs.
