The words of the Old Covenant/Old Testament Scripture spoken by Abraham, beautifully and meticulously, prophesy the ultimate provision of the coming of the One Who would give His life for our salvation.
As Isaac wondered out loud to his father, “Where is the sacrifice?”, Abraham answered,
“God will provide Himself a Lamb” (Genesis 22:8, KJV)
In the New Testament Scripture, the ultimate sacrifice comes through Jesus, this promised One. His conception and birth is announced to Joseph in a dream preparing him for what is soon to come regarding his beloved Mary, “And she shall bring forth a son, and thou shalt call his name Jesus: for he shall save his people from their sins. ” (Matthew 1:21)
When Jesus has been born, grows up and becomes a man, beginning His three and a half year ministry on earth, John the Baptist proclaims, “Behold, the Lamb of God who takes away the sin of the world!” (John 1:29, NKJV)
The promises of Jesus include provision both in this life (Matthew 6:25-33; Philippians 4:19) and in the life to come. (John 14:2-3)
