God is Holy and requires holiness from us. This is absolutely impossible to achieve apart from the finished work of Jesus in Calvary. God’s salvific work is a past, present and future work. He made us holy through justification. He is making us holy through sanctification. And He will make us holy through glorification.
Listen to what God will do in this powerful work of glorification.
Philippians 1:6 says, “And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.”
