“For of His fullness we have all received, and grace upon grace” (John 1:16).
The verse speaks of how important Christ has become to us, who believe Him unconditionally. Believing Him without limitations helps us fully grasp and experience the substance of the verse; there should be no ifs and buts when believing Him. It encapsulates the saying “all things are possible to him that believes.” John who wrote of His fullness by the guidance of the Holy Spirit experienced it throughout his life thoroughly by believing in it.
The verse has two elements spoken in reference to us. But first the phrase “His fullness” must be understood. It means there’s nothing lacking in Him that we should be in want. Jesus has everything in Him pertaining to our life and eternity. He is all that is enough for us; in fact, more than enough for us. It is exactly here that our faith in Him is tested and often many church-goers, even pastors fail in it. “His fullness” is so abounding that even in dire need or lack we do not need anyone, but Him. This Paul did when he sought Him to remove the thorn in his flesh and was instead bestowed with grace (2 Cor. 12:7-9). On the contrary, when we go beyond Him in search of possibilities, i.e. we go toward the works of the flesh and mind we did not understand His fullness.
The two elements spoken in reference to us are forgiveness of sins and intensified (enhanced) grace. We receive forgiveness of sins by believing in His fullness and grace upon grace by believing in the same. His fullness is characterized by the fullness of Deity existing in Him (Col. 2:9). As we believe in Him unconditionally throughout the various moments of our life, we receive grace after grace symbolizing the receiving of greater grace (or, we receive grace for the grace received signifying greater grace). You are in the body of Christ if you are a recipient of greater grace which has no part with your anxieties, feelings, thoughts, works, ways and earthly choices.
