Jesus wasn’t big on resolutions … at all.

“I say to you, do not swear at all.” (Matthew 5:33-37).
The Bible is full of warnings about vows and expectations on ourselves or others. The reason? Instead of asking God to meet our needs, a vow (or a New Year’s resolution) puts us in the position of swearing before God that we’re going to accomplish something on our own.
Besides, it’s presumptuous. Consider James 4:13-15 – “Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain: Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. For that ye ought to say, If the Lord will, we shall live, and do this, or that.”
The Jewish ceremony of Kol Nidrei on Yom Kippur declared all our vows as annulled and “made void.” And for those who “place no confidence in man,” the Kol Nidrei should apply every day.
Thankfully, God provides another way:  “Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God” (Phil. 4:6).
