And the LORD spoke to Moses, saying, "Speak to all the congregation of the children of Israel, and say to them: 'You shall be holy, for I the LORD your God am holy. Leviticus 19:1-2

God’s people are called to be holy. Why? Because God is holy!

Our lack of holiness is a sin against a direct command of God, resulting in the fact that we deserve God’s judgment.

Praise God that Jesus lived, died, and rose to save us from the penalty of our sin and to declare us to be holy in God’s eyes—even though in practice, even the saved, are still not holy as God is holy. Praise God for justification! (Justification is a work solely of God)

Praise God also that He does not leave us in an unholy condition. It is through the life-long process of sanctification that believers are progressively transformed into the holy image and likeness of Christ. This is a work of God that depends in part on the cooperation of each believer.

One day when we are glorified (either when we die or when Christ comes again), we will actually be made holy. Glorification is solely a work of God.
