Jesus was not shy in declaring who He was, nor in calling on witnesses to testify to who He was, even witnesses who were long gone, including Abraham. “ ‘Your father Abraham rejoiced to see My day, and he saw it and was glad’ ” (John 8:56, NKJV).
Why was Abraham’s witness so important that it was included in John’s gospel? (Gen. 12:3, Gen. 18:16–18, Gen. 26:4, Matt. 1:1, Acts 3:25.)
