No person ever comes to see his need of a Savior until he has first come to see himself as a condemned sinner before God. And it is only when we come to see ourselves as we are in the sight of a holy God that there is hope of salvation.
The self-righteous do not see their need of a Savior. What would He save them from? What have they done that is so wrong? This is the way their reasoning goes. It is only when we begin to appreciate the holiness and righteousness of God that it dawns upon us that our condition is hopeless without a Savior.
Strange, is it not, that so many people have pictures hanging on their walls of our Lord crowned with thorns or hanging on a cross, yet do not really know Him as a Savior, their own Savior.
But when we have been convicted of our sin and our hopeless condition before God, we are ready to take in the words spoken by Paul to the trembling jailor at Philippi:
“Believe on the Lord Jesus Christ, and thou shalt be saved” (Acts 16:31). source
