Leviticus 20:7 "Consecrate yourselves and be holy, because I am the LORD your God. Keep my decrees and follow them. I am the LORD, who makes you holy.
God's call to us in Leviticus is a call to holiness. To be holy is to be set apart. He calls us to be set apart unto Him who is holy. Our holiness comes from Him. We don't just do holy; we be holy. We be holy because of whose we are. And out of who we are, then we do holy. It's an inner work that God is doing and we work it out from His work on the inside of us. His Word gives us a picture of what that looks like and as we continue to look at that picture, we are transformed into that image by the Spirit of the Lord living in us.
Colossians tells us this: Once you were alienated from God and were enemies in your minds because of your evil behavior. But now he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation--if you continue in your faith, established and firm, not moved from the hope held out in the gospel (1:21-23). . .Christ in you, the hope of glory (1:27). 1 Thessalonians 5:23, 24 says this, May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. The one who calls you is faithful and he will do it. Praise God!
How do we respond? Philippians 2:12, 13 says, Therefore, my dear friends, as you have always obeyed--not only in my presence, but now much more in my absence--continue to work out your salvation with fear and trembling, for it is God who works in you to will and to act according to his good purpose. We could not save ourselves, but we have been given a living hope, a gift of salvation from God Himself, and what He put in us, we are called to walk out. Practical James tells us to walk this way: Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you. So, we choose to yield to the word within us and then we can walk out that salvation. He goes on to say, Do not merely listen to the word, and so deceive yourselves. Do what it says. Anyone who listens to the word but does not do what it says is like a man who looks at his face in a mirror and, after looking at himself, goes away and immediately forgets what he looks like. But the man who looks intently into the perfect law that gives freedom, and continues to do this, not forgetting what he has heard, but doing it--he will be blessed in what he does. And this, my friend, is why I keep looking into this word. It is my hope, my hope in Christ, the living Word. I want the word to be made flesh in me--Christ in me, the hope of glory!
