When we where without Christ as sinners as the world that doesn't know the Lord we where blinded by the enemy of our souls by our own sin and selfishness.
But when we started seeking and hungering desiring like little children hearts full of faith love and tenderness little by little God enlightens and eliminates us through His Holy Spirit and shows us what His desires we are no longer clouded and blinded our eyes are suddenly through constant fellowship and in His word staying close to His side so when the enemy does come we see him for what he is and see through the eyes of th Holy Spirit what is wrong and evil sin what we allow and welcome into our lives. Jesus gives us the strength and discernment to overcome sin evil and temptation.
