Grace is a spiritual force that empowers us to live above sin and to walk in Holiness. We are justified by grace through faith not of works lest anyone should boast. So we have a Grace jackpot that keeps us in God if we would belief it and receive it by faith as we received Christ Jesus. Many have come to terms with this truth and are growing into the fulness of what Jesus did for them on the cross but unfortunately they are oblivious of the need to position themselves for the manifestation of His Grace.
There are many things to discipline such as the mouth, thought, actions e.t.c.
All of these requires a conscious yieldedness to Grace, for empowerment to stay above sin and sail triumphantly through life. If we cannot be yielded to Grace, then we cannot receive and enjoy the fulness of His blessings and benefits. Romans 6:15-22
