Once rescued and redeemed by the blood of the covenant which establishes a New Covenant relationship, means we are maintained in this Covenant when we live a life of Worship the Lord Jesus who died for us, otherwise if we fail or stop Worshiping Him then there's a danger of going back into slavery.......
Let us strive to fix our eyes on Jesus who is the leader and perfecter of our faith. (Heb 12:2)
