As a Christian, you are set apart. Not because you have done anything special, but because of what Jesus has done for you! Are you living your life as though you are set apart by grace?
Paul writes in Romans 6:1-2, "What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We are those who have died to sin; how can we live in it any longer?"
While Jesus' sacrifice justifies us in an instant, we don't stop sinning or struggling with temptation overnight. It takes time, sacrifice and effort to live for the Lord daily. We can't do it through our own determination or strength: we must continually seek the Lord's strength to live for Him.
