This list gives you King James Version verses about keeping promises, for anyone who has said yes to something and now needs to know what God expects of their word. Whether you are trying to honor a commitment that has become inconvenient, or trying to become someone whose word can be trusted, these passages point to the same thing: God is faithful, and He calls His people to reflect that faithfulness. The verses below are grouped by situation, so you can find the one that fits the moment you are in.
Verses for the Morning You Are Tempted to Back Out
Some of the hardest promises to keep are the ones you made when things looked simpler. These verses speak to the moment when the commitment feels heavy and walking away seems easier than following through.
Psalm 15:4
In whose eyes a vile person is contemned; but he honoureth them that fear the LORD . He that sweareth to his own hurt, and changeth not.
(KJV)
This psalm describes the kind of person who may dwell with God, and one mark is that they keep their word even when it costs them. Try naming one specific promise you are tempted to break today, and decide before the day begins that you will honor it.
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.
(KJV)
Israel’s law treated a vow as binding, not as a casual intention. Before you respond to a request this week, pause and ask whether you can truly follow through, so that the word you give is one you intend to keep.
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.
(KJV)
Solomon warns that it is better not to vow than to vow and not pay. If you have already spoken a promise, write it down and set a reminder, so that your follow-through matches the words you have said.
Verses on God Who Keeps His Word
Our faithfulness rests on God’s own faithfulness. These verses remind you that the One who calls you to keep your word has never once failed to keep His.
Deuteronomy 7:9
Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations…
(KJV)
Moses describes God as the faithful God who keeps covenant and mercy with those who love Him. When you feel that your commitment is slipping, remember that God’s reliability is the foundation you are building on, not your own strength.
Numbers 23:19
God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it ? or hath he spoken, and shall he not make it good?
(KJV)
This verse says God is not a man that He should lie, nor the son of man that He should repent. Read it slowly, and let it steady you when your own words feel unreliable, since God’s word does not change with His mood.
Hebrews 10:23
Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)
(KJV)
The writer urges believers to hold fast the profession of their faith without wavering, because He that promised is faithful. Choose one area where you have been wavering, and hold it firmly today by reminding yourself who is making the promise.
Verses for Building a Reputation People Can Trust
Keeping promises is not only about individual moments; over time it shapes the kind of person others come to rely on. These verses speak to character that is steady and consistent.
Proverbs 25:19
Confidence in an unfaithful man in time of trouble is like a broken tooth, and a foot out of joint.
(KJV)
Proverbs compares trusting an unfaithful person in a time of trouble to a broken tooth or a lame foot. Notice where your word has become unreliable to others, and make small, dependable steps to rebuild their confidence.
Psalm 15:1-5
1 LORD , who shall abide in thy tabernacle? who shall dwell in thy holy hill? 2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart. 3 He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour. 4 In whose eyes a vile person is contemned; but he honoureth them that fear the LORD . He that sweareth to his own hurt, and changeth not. 5 He that putteth not out his money to usury, nor taketh reward against the innocent. He that doeth these things shall never be moved.
(KJV)
This passage lists the traits of one who can stand in God’s presence, including swearing to one’s hurt and changing not. Read it as a portrait to grow into, and ask God to make your yes and your no dependable.
Matthew 5:37
But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
(KJV)
Jesus says let your yes be yes and your no be no, without needing oaths to prove you mean it. Practice being direct in small matters this week, so that your ordinary word becomes enough without embellishment.
Verses for Keeping Your Word When It Costs You
Some promises are kept at a price: lost time, lost comfort, or lost pride. These verses encourage you that faithfulness in costly moments is not wasted before God.
Galatians 6:9
And let us not be weary in well doing: for in due season we shall reap, if we faint not.
(KJV)
Paul says not to be weary in well doing, for in due season you shall reap if you faint not. When a promise has become tiring, look for the small next step you can take, and trust that persistence in good things is not lost.
Romans 12:9
Let love be without dissimulation. Abhor that which is evil; cleave to that which is good.
(KJV)
Paul writes that love must be without dissimulation, which includes keeping your word in relationships. Pick one person you have promised something to, and make your follow-through a simple act of genuine love.
How to Use These Verses
Start by choosing one verse that speaks to a promise you are currently carrying. Write the reference on a card or in a notebook and place it where you will see it during the day, such as near your calendar or on your phone’s lock screen. Reading the verse aloud before you respond to a request can help you pause and decide wisely before you commit.
Pray the verses instead of only reading them. Turn Numbers 23:19 into a prayer of thanks that God is not fickle, or ask God to shape your Matthew 5:37 integrity in a specific conversation. Returning to these passages each week, especially before making new commitments, helps your word grow more trustworthy over time.
A Short Prayer for keeping promises
Lord, You have never broken Your word, and I thank You that Your faithfulness is steady when mine is not. I confess the times I have said yes too quickly, or let a commitment drift because it became inconvenient. Give me wisdom to speak carefully, courage to follow through when it costs me, and honesty to tell the truth when I cannot keep what I promised. Make my yes be yes and my no be no, for Your glory and for the good of the people who trust me. Amen.
