1 Peter 1:13-16 (NASB)
13 Therefore, prepare your minds for action, keep sober in spirit, fix your hope completely on the grace to be brought to you at the revelation of Jesus Christ. 14 As obedient children, do not be conformed to the former lusts which were yours in your ignorance, 15 but like the Holy One who called you, be holy yourselves also in all your behavior; 16 because it is written, "YOU SHALL BE HOLY, FOR I AM HOLY."
There seems to be a prevailing thought among many people who are part of the church. People who say, "yes I am a Christian" but then still have some bad traits, habits, or ways of doing things that is less than what God wants or expects from those who love Him. They seem to think that the grace of Jesus is free and it is so nothing is required on their part. We find in this writing from the Apostle Peter what God does expect from anyone who places faith in Jesus. He looks for us to be holy. Most Christians do not think of themselves as being holy, but this is what we are called to, holiness.
Holiness does not happen by accident. Holiness involves your total being. Note Verse 13 to. "fix your hope" on Jesus Christ. This is saving faith in Jesus Christ. With that saving faith then comes this need to prepare the mind and keep sober in spirit. There in verse 15 is the key word. "Behavior. Our behavior is or should be totally completely changed by our relationship with God.
I made the statement in church Sunday that some people only get part of the message. We stress so much the fact that you come to Jesus Christ in faith "just as you are" you do not need to change before coming to humble yourself and ask Christ to forgive you. We even use the great hymn Just as I Am when we offer an invitation to come to Christ. We stress this fact that no change is needed that I am afraid some get the impression that coming "Just as I am means you can stay Just as you are." This is false. Coming to Christ means everything about you should change immediately.
Paul says in 2 Cor 5:17 that we are a "New Creation In Christ." This means everything has changed. That Key word in the 1 Peter passage at the top of the page says it plainly. All of our behavior is to be holy. What behaviors do you have that might be considered less than holy? What actions do you do that would bring reproach on the work of God?
Our time on earth is limited and our behavior does matter. The Bible is very plain in this matter. If you are "In Christ" we are called to holiness. BE HOLY!
