11 Do this, knowing the time, that it is already the hour for you to awaken from sleep; for now salvation is nearer to us than when we believed. 12 The night is almost gone, and the day is near. Therefore let us lay aside the deeds of darkness and put on the armor of light. Romans 13:11-14 (NASB) (Read 13-14 on the site)
Genuine Christians are marked in this life by a spiritual journey that God uses to sanctify them. Sanctification is the process whereby God removes Christians from the pollution of the world and conforms them unto His holiness. I have had some so-called “Christians” attempt to deny this as true for all Christians. They claim that only God is Holy and there is no call by God for His people to repent and mortify their sins. Regardless, the Word of God does contradict what they say.
