Psalm 1:3 KJV — And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.
The “he” in Psalm 1:3 is the person who was being talked about in Psalm 1:1
He walks not in the counsel of the ungodly, he stands not in the way of sinners, he sits not in the seat of the scornful.
He delights in the Word of God and meditates on it day and night.
Why?
No reason is given. This is just who he is. This is his identity.
And when he does things that flow out of his identity, they always succeed.
If what you’re doing isn’t working or bearing fruit, check to make sure that your actions are in agreement with your identity.
