This list gives you Bible passages about keeping promises, arranged by the moments when it is hardest to follow through: the early commitment, the long wait, the day you feel like backing out, and the words you want to speak to others. It is written for anyone who has said yes to something and needs to remember what God says about faithfulness. These verses share one thread: a promise is a serious matter, and the God who keeps every word he gives is the pattern and the help for ours.

A man had two sons, and he came to the first, and said, ‘Son, go work today in my vineyard.’ 29 He answered, ‘I will not,’ but afterward he changed his mind, and went. 30 He came to the second, and said the same thing. He answered, ‘I’ m going, sir,’ but he didn’t go. 31 Which of the two did the will of his father?” They said to him, “The first.” Jesus said to them, “Most certainly I tell you that the tax collectors and the prostitutes are entering into God’s Kingdom before you.

How to Use These Verses
Write the references that matter most to you on a card, in a notebook, or as a phone note, and keep them where you will see them when you make decisions. Choose one verse from the section that fits your current situation and read it slowly for a few days. Reading only a single passage each week often does more than skimming the whole list once.
Pray these verses back to God rather than just reading them. Ask him to show you which commitments need attention, to give you the strength to keep them, and to reveal any promise you should release honestly. Bring a specific name or task into your prayer so the verse stays connected to real life.
A Short Prayer for Keeping Promises
Lord, you are faithful in everything you have said, and I am grateful that your word can be trusted. You know the commitments I have made, the ones I am keeping and the ones I am tempted to drop. Show me where I have been careless with my words, and give me the courage to speak honestly when I cannot do what I once agreed to. Strengthen my resolve on the slow days, and remind me that you are present in every small faithful step. Amen.
