To be blessed by someone is an encouragement to your soul. It validates you and it confirms your purpose.
In Psalm 1, God gives a blessing to the man who follows God. This man doesn’t take advice from wicked people. He doesn’t sin because his friends are sinning and he doesn’t degrade people who are different from himself.
The blessed man delights in God’s word and he thinks on those things day and night. He is like a tree with a healthy root system because he is planted by the water of life. His tree produces leaves and fruit. It is a tree with life. Whatever he does prospers because he knows what kind of tree he is and he doesn’t try to be something he isn’t. His has a purpose.
The wicked man is all over the place. A strong wind blows and he chases the chaff that is blowing away from his reach. He is not happy with who he is and he wants to be something else. There is not stability in his life.
The Lord watches over the blessed man because his hope is in the Lord.
