In Colossians 3: 1-17 we read how that if we are in Christ we need to be acting and thinking as Christ would have us do.
Setting your mind on the things above, not on the things that are on earth. 8 But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips. 12 So, as those who have been chosen of God, holy and beloved, put on a heart of compassion, kindness, humility, gentleness and k]patience; 13 bearing with one another, and forgiving each other, whoever has a complaint against anyone; just as the Lord forgave you, so also should you.
There is no time like the present to make changes. The new year is a good time, like we all know, to make those resolutions. But maybe instead of the resolutions where we promise ourselves what we are going to do, we should be deciding to stop doing those things that are not suitable for a Christian’s walk or for our health.
