Let’s see what a testimony is. The following Scripture passages will help us to understand the origins of this word.
Luke 22:20 “This cup which is poured out for you is the new covenant in My blood.” As Jesus institutes the Lord’s Supper with His disciples, He draws their attention to the cup being shared among them, explaining its significance. It represents what He calls “the new covenant” in His blood. Keeping that in mind, turn back to Exodus 24:8, “So Moses took the blood and sprinkled it on the people, and said, ‘Behold the blood of the covenant, which the Lord has made with you in accordance with these words.’ ”
The Old Testament is the testimony, or, words, containing the description of God’s covenant relationship with people whom He had sought out. Old Testament means “Old Covenant.” It was the only covenant until the time that God sent forth His only begotten Son, Jesus, to allow His own blood to become the sacrifice required to initiate God’s covenant relationship with people whom He seeks a relationship. “For without the shedding of blood there can be no remission of sins.” (Hebrews 9:22)
Thus, the Old Testament contains the language of the covenant relationship between Holy God and sinful man. It contains the information necessary to understand how sinful people can experience a real and intimate relationship with a holy God, in spite of our sinfulness. Blood was required. Sacrifice to atone for sin. The blood of innocent animals paid the penalty brought about by our sin. Today, we live in a time when sin is no longer recognized. So, people struggle with understanding or accepting its consequences. Problem is, God is still God, He is still holy, and our ignorance does not exempt us from the fact that we need saving from our sins.
Enter, Jesus Christ, God’s only begotten Son. He offered Himself to become the perfect sacrifice for sin, once and for all. What made Jesus perfect? His sinlessness. “He who knew no sin was made to be sin on our behalf, so that we might become the righteousness of God in Him.” (2 Corinthians 5:21) The very night that He was arrested, and His sacrifice of blood was about to occur, He took the bread and the cup of wine, and presented these elements to His disciples as symbols of His body which would be broken for them, and His blood which would be spilt for them. No longer would the “blood of the covenant” come each year from innocent animals. Now, the “Lamb of God” would take away the “sins of the whole world.” That is the “New Covenant” in His blood. The New Testament contains the language, the story, of the “New Covenant.”
When a sinful person receives the gift of forgiveness of sins, and eternal life as God’s gift to all who profess Jesus Christ as Lord and Savior, then they too enter into a covenant relationship with Holy God. The gospel is the story of salvation through Jesus Christ and His atoning sacrifice for our sins. When the gospel, the story of salvation comes to us, then we become part of the gospel story. Now, you too have a story to share. The story of how you were saved is your testimony.
