I will sing your praises forever and will always keep my promises. (Psalm 61:8)

Always is a pretty tough word to keep. When was the last time you broke your promise? The punishment for such a breach is quite severe:

The judges shall investigate thoroughly, and if the witness is a false witness and he has accused his brother falsely, then you shall do to him just as he had intended to do to his brother. Thus you shall purge the evil from among you.   The rest will hear and be afraid, and will never again do such an evil thing among you.  (Deuteronomy 19:18-20)

A false witness will not go unpunished, and he who tells lies will perish. (Proverbs 19:9)

It could be weeks, months, or years; or just in the last few minutes. It could have been huge, or it could have been small. Maybe you ran out of time. Or it got too complicated. Or it was hurting too much. Or maybe, you had no intention of keeping your promise in the first place. Consider the following:

Who may stay in God’s temple or live on the holy mountain of the Lord? Only those who obey God
and do as they should. They speak the truth and don’t spread gossip; they treat others fairly and don’t say cruel things. They hate worthless people, but show respect for all  who worship the Lord.
And they keep their promises, no matter what the cost. (Psalm 15:1-3)

He who walks in integrity walks securely, but he who perverts his ways will be found out. (Proverbs 10:9)

Not one of the good promises which the LORD had made to the house of Israel failed; all came to pass. (Joshua 21:45)

Faithful is He who calls you, and He also will bring it to pass. (1 Thessalonians 5:24)

Whether keeping your word, or your promises, may your character reflect the Lord Jesus Christ.
