John 19:30 (KJV) -- “It is finished: and he bowed his head, and gave up the ghost.”
Jesus said, “I have glorified thee on the earth: I have finished the work which thou gavest me to do” (John 17:4 KJV). The entire work had been finished of what the Father had given to the Son. The debt had been paid in full to redeem men from their sins. The obligation that was required of Him by the Father had been completed.
Acknowledgement of victory
A person who has experienced defeat -- you probably will hear only a whimper from them. However, the victor exclaims his victory loud and clear. “It is finished!” Jesus shouted out victory that reached the place of the cross and beyond. The echo from His cry still resounds throughout our world today. It is finished. Really, what had taken place was the new covenant emerging according to Hebrews 8:6 (KJV) -- “But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises. For if that first covenant had been faultless, then should no place have been sought for the second.”
Later in God’s word, we read this passage: “For all the promises of God in him are yea, and in him Amen, unto the glory of God by us” (2 Corinthians 1:20 KJV).
His obedience fulfilled
It was an acknowledgement of His accomplishment through obedience to His Father. “Believest thou not that I am in the Father, and the Father in me? The words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works” (John 14:10 KJV).
To say, “It is finished,” to the Father's assignment was a life of being made flesh, being made in the appearance of a man, taking on the very nature of a servant, being humble and suffering. As a result, Jesus ushered in the new covenant of promises. Hallelujah!
The new era with purpose, promise
We are to live our lives focused and disciplined to the purpose of His promises, which provide opportunities for greater victories to experience a successful way of living. To achieve this, one would have had to receive revelation of the power of God that is in you. Ephesians 1:17 (KJV) reminds us, “That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him.”
Let us not forget this scripture, “But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth” (Acts 1:8 KJV).
This is why the enemy works hard to keep you from realizing who you are in Christ. Through faith in Christ Jesus, we are the children of promise. “Now we, brethren as Isaac was, are the children of promise” (Galatians 4:28 KJV).
Let’s look into the Bible to remind ourselves about who we are in Christ. “And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise” (Galatians 3:29), and “For all the promises of God in him are yea, and in him Amen, unto the glory of God by us” (2 Corinthians 1:20 KJV).
Therefore, when we allow the Word of God to become increasingly more powerful and real to us, we will walk in a new level of spiritual authority as heirs.
