A common (and 100% correct) argument used to refute theistic evolution is the fact that those who don't believe Moses will not believe Jesus. When Young Earth Creationists (which I am one) make this argument, they are quoting Jesus directly, from John 5:46. Again, this is 100% correct, but not just for the reasons that creationists give.
Most of the time, when a creationist invokes John 5:46, they're talking exclusively about believing what Moses wrote concerning the origin of everything. And while they are right that you need to believe what Moses wrote concerning the origin of everything in order to believe Jesus, where they go wrong is the exclusion of the rest of what Moses wrote.
Some will point to Genesis 3:14-15 as being where Moses wrote about Jesus. This is indeed a prophesy about Jesus written by Moses, but there is so much more that Moses wrote than a single prophesy in a single book. In fact, Genesis as a whole is a mirror image of the Messiah (both literally and figuratively). The literal part because of the fact that Hebrew scrolls are striped (to guide the scribes on where to write) and pierced (to bind the different scroll pieces together to make a single scroll) just as Jesus was striped (by whips) and pierced (by thorns and nails). The figurative part because many of the lives of those who are recorded in Torah mirror the life of Jesus.
Here are some examples of people who's lives mirrored that of Jesus:
- Noah's Ark saving Noah and his family, and two of every kind of animal from God's judgement is a mirror of Jesus saving us from God's coming judgement.
- Noah's Ark being the only means of salvation from God's judgement is a mirror of Jesus being the only means of salvation from God's coming judgement.
- Isaac being born by the Spirit of God is a mirror of Jesus also being born by the Spirit of God.
- Isaac nearly being sacrificed is a mirror of Jesus actually being sacrificed.
- Joseph being betrayed by his brothers is a mirror of Jesus being betrayed by a close friend.
- God using the treason against Joseph to save the world is a mirror of God using the treason against Jesus to save the world.
- Joseph is never recorded to have sinned even once, mirroring Jesus never sinning once.
In addition to that, many of the things which are found in Moses' writings point directly to Jesus, including:
- Jesus is the Passover Lamb that caused God's wrath to pass over us (the Passover meal).
- Jesus is the Unleavened Bread, leaven representing sin (Feast of Unleavened Bread).
- Jesus is the First Fruits from the dead (Feast of First Fruits).
- Jesus is the Sabbath (seventh day) rest.
- Jesus is the Atonement for our sins (Day of Atonement).
There is quite a bit more in Torah that points directly to Jesus than what I've listed here. Go search for yourself! As you can see from this sample, Genesis is only a small part of what it means to "believe Moses". If you believe Moses concerning Genesis, but not the rest of what he wrote, then you really don't believe him. For nearly everything recorded in Torah is a picture of Jesus our Lord and savior! In fact, according to the biblical definition of faith, merely believing what Moses said is not good enough. You must also obey him!
Again, believing Moses about Genesis, but not the rest of what he wrote is not believing Moses. Believing Moses only starts with believing Genesis. And believing all of what Moses wrote without obeying him is also not believing Moses. For Moses told us how to live holy (set apart) lives dedicated to God. Obeying him shows that you believe he was truthful concerning holiness, while disobedience shows that you believe he was mistaking or lying about holiness. And Jesus obeyed Moses! Isn't it interesting that those who do not obey Moses (who wrote exactly what God commanded him to write [Exodus 24:4]) also do not obey Jesus? And that those who cherry-pick Moses' teachings also cherry-pick Jesus' teachings?
