When we understand that Isaac was an adult who willingly offered himself as a sacrifice in obedience unto his father, we see in him a type of Messiah Yeshua in the clearest terms. While no sacrifice would be comparable to the one Jesus made when He gave Himself up for the sin of the world, Isaac, like Yeshua, knowingly offered up his own life on that altar, fully expecting to die there. Kirt Schneider
