What brought about separation between man and God is SIN. Living above Sin is possible through the grace of God that was made manifest throgh Christ and made available to us.
He took upon Himselves all our sins.
We need to continuouslty orking towards perfection by devoting ourselves to studying the word of God and not give room for Devil to penetrate into our live.
We need to continue to ask for grace to live above sin and live a righteous life that pleases God.
We need to also watch and pray. Watch the type of friend we keep and be mindful of the thought that we allow to dominate our heart.
