On Sunday we looked at this verse together and saw how just as God freed his people from slavery in Egypt, in Christ's death on the cross he has redeemed us from slavery to sin. But just as the Israelites getting of Egypt had a lot of Egypt left for God to get out of them, we saw that the Christian life is also a lifelong work of God redeeming us from the power and presence of sin.
I've found this video a helpful reminder that this is what living the Christian life is all about, and that it can sometimes be a painful process, but is always for our good, and God's glory.
