We are saved by grace through faith, but the faith must be genuine. To truly believe is defined by repentance and discipleship. Only disciples of Christ can call themselves Christians. Grace is the power of God released to walk above the corruption that is in the world, and also the power released to fulfill everything the Lord planned for us to fulfill in life. Grace is not at all the cover for our weaknesses while we continue in sin and in disobedience to the call of God.
