Before you answer the question, what does prosper mean from a biblical perspective? In many circles today, prospering means making more money, getting a better job, a bigger house, a better car, a larger church, etc. In this context, prosper implies that God will bring forward something good from whatever is undertaken if you meet the conditions.
The psalmist tells us, “Blessed is the one who does not walk in step with the wicked or stand in the way that sinners take or sit in the company of mockers, but whose delight is in the law of the Lord, and who meditates on his law day and night. That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither— whatever they do prospers.” Psalm 1:1-3
If you are meditating continually on God’s word, storing His word in your heart, and living according to His word, you will live a prosperous life.
