This is a sermon comparing an upright walk with a perverted walk.
One of the most powerful biblical pictures of Jesus Christ is as our Shepherd. Here in Psalm 23, we see Him as the Good Shepherd who cares for the sheep.
This psalm gives a graphic picture of the suffering King. It is likely that David initially spoke/penned these words to describe a personal affliction. Yet, the Lord gave him the words in such a way that it would be a prophetic explanation of the physical and spiritual sufferings that would be endured by the Son of God.
God never promised to remove all trials or to give us heaven on earth. However, He has promised that the man who separates himself from the world and gives himself over to the Lord will be blessed.
It is time for us to return to the battles of yesteryear, when the enemy was Satan, the stakes were eternal, the captain was the Lord Jesus, and the victory was certain.
