"In him (Jesus) you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory."
-- Ephesians 1:13,14
Grace is the invitation to come home to your Heavenly Father. God loves you and is FOR you, and wants you to experience the life He designed you for - life with Him, not apart from Him. Taking a step with this G involves accepting the gift of new life, love, and forgiveness that God offers to us only through Jesus Christ. Once we’ve done that, our next step is to go public with our faith through baptism. We never stop growing in grace as we learn to see our Father at work in us and through us as well as His generosity to us.
Grace is the beginning of a journey where our falls and His faithfulness meet more and more until we would never doubt His love and acceptance of us.
