Throughout history man has failed to uphold his end of covenant with God. For that reason Christ had to be made like us, fully human. Jesus completely fulfilled the old covenant and invites us to partake in its benefits. Through him we are fully cleansed, full of God's peace, fully at peace with God and abounding in his grace. We cannot add anything to the finished work of Christ. His grace is fully sufficient. It is our role to receive it as the gift that it is and enjoy it.
