“Don’t worry about the wicked or envy those who do wrong. For like grass, they soon fade away. Like spring flowers, they soon wither.
Trust in the Lord and do good. Then you will live safely in the land and prosper. Take delight in the Lord, and He will give you your heart’s desires.”
Psalms 37:1-4 NLT

In Psalm 37, David picks up again his thoughts about wicked people, and in the process he contrasts their behaviour with that of God’s people. Again and again in this Psalm he points out what “the wicked” are doing wrong and how their lives will end, and then provides a contrast of how Godly people live their lives, adding in words of advice where appropriate. The dichotomy between the two types of people is stark and extreme and it is clear that Godless lives will not end well.

The instruction, “Trust in the Lord and do good” acts as a doorway into a gold mine of instructions, thoughts and behaviours. Just reading this inscription above the door knocker will be ineffective on its own; the door has to be opened and the nuggets within removed, consumed, and acted upon, to provide all that is necessary for life in communion with our Heavenly Father. And a relationship develops with God, so close that “Trust” becomes second nature.
The Psalmist also encourages God’s people to “do good”. Two words almost hidden and overlooked after the impact and boldness of “Trust in the Lord”. But nevertheless an important part of life as a Christian is to do good deeds to and for those around us in our communities and families. Galatians 6:10 reads, “So then, as we have opportunity, let us do good to everyone…”. And there are many other similar encouragements spattered throughout Holy Scriptures.
The end result of living our lives God’s way though, is clear. Safety and prosperity will result. There is always a tendency to interpret the word “prosperity” from a financial perspective. But it’s so much more than that. Think about the riches of being healthy – mentally, physically, emotionally and spiritually. Think about being blessed by the richness of having a loving family. And of course we mustn’t overlook the prosperity God’s people will find in their ultimate spiritual home.
We can’t leave these verses without considering the last few words. As we delight ourselves in the Lord, and align our hearts, our thoughts, with those of Him, we will find that any worldly materialistic desires will be eclipsed by what really matters. God-values such as love, compassion, mercy, grace, righteousness and so on will infuse our ways of life and waking thoughts. And we don’t worship a stingy God – He will pour out bountifully all we need.
Psalm 37. Essential reading for everyone. We ignore or disregard these verses at our peril.
