"In God I will praise his word, in God I have put my trust; I will not fear what flesh can do unto me." (Psalm 56: 4)
For many of us, we have a fear problem.
But this fear has no business being in our lives.
"There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love." (1 John 4: 18)
This perfect love is based on our growing understanding that God loves us as much as He loves Jesus:
"This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus." (1 John 4: 17, NIV)
Returning to Psalm 58: the first part reads "I will praise His word."
His Word is Jesus:
"In the beginning was the Word, and the Word was with God, and the Word was God." (John 1: 1)
And we can take God at his Word, since His Word is going nowhere:
"Heaven and earth shall pass away: but my words shall not pass away." (Mark 13: 31)
Because we trust in His Word, we do no have to fear any flesh:
"The voice said, Cry. And he said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field:" (Isaiah 40: 6)
"The grass withereth, the flower fadeth: but the word of our God shall stand for ever." (Isaiah 40: 8)
The Word of God, made flesh, overcame the world (John 16: 33), and in the Word we are more than conquerors (Romans 8: 37)
And His Word heals us, too:
"He sent his word, and healed them, and delivered them from their destructions." (Psalm 107: 20)
It's all about the Word made flesh (John 1: 14), and when you trust in the Word, then no flesh, no man can cause you any fear! (Hebrews 13: 6)
