My personal take in New Years Resolutions is that they are, generally, pretty useless. Yet not a year goes by that I don’t make a few. I know there are some far better than I in keeping resolutions. But many aren’t.
The psalm, which is the first psalm in the Bible reading program for the year, puts matters into perspective. I copy it, although I would suggest you commend it to memory:
Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers; but his delight is in the law of the LORD, and on his law he meditates day and night. He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers. The wicked are not so, but are like chaff that the wind drives away. Therefore the wicked will not stand in the judgment, nor sinners in the congregation of the righteous; for the LORD knows the way of the righteous, but the way of the wicked will perish.
If nothing else, the psalm is simple. Prospering and bearing fruit is the fruit of avoiding sin (walking in righteousness) and delighting in the word of the Lord. Of course, delighting in the word of God implies walking accordingly, for one cannot delight in the Scriptures and not obey them (this is the point of verse 1). But all prosperity that comes from God begins here. Therefore, before any other resolutions, settle this one. If you delight in the Lord, you will prosper. What exactly that may look like may not be what you expect, but you will prosper. If you do not, whatever other “prosperity” or “success” you find will in the end be chaff, blown away in that day when all things are revealed to be what they are.
