Gospel in the OT

Scripture taken simply as an instruction manual would probably be one of the most discouraging self-help books this side of the resurrection. All of scripture will point you to Christ and his love for you :)

From an interview with Dane Ortland:

Where is the gospel in Proverbs (or James)?

There is no magic formula to ‘find’ the gospel in Proverbs. Rather, if we read Proverbs as wise words from a father who loves his children too much to let them ruin their lives through ignorant folly, we will receive it as God means us to, and be strengthened in a way that is grace-flavored.

And remember, from a macro-perspective, Jesus is the ultimate wise man. Paul said that Jesus "became for us wisdom" (1 Cor. 1:30). Jesus is the wise man, and we fools, united to him by faith, share in that wisdom.

Where is the gospel in Leviticus?

All over the place. Leviticus is an elaborate accounting of the sacrificial system that God mercifully instituted for Israel, to atone for their sins. It is virtually impossible to plunk down into a random place in Leviticus and not see God’s gracious provision of a way out for filthy people.

And Jesus himself brought that entire sacrificial system to fulfillment. The New Testament tells us Jesus was not only the priest who offered the sacrifice, he was also the sacrifice itself, the lamb—and he was even the temple in which the priest offered the sacrifice. As we read Leviticus as Christians, then, we can be ever mindful of what all those bloody sacrifices were anticipating.

Where is the gospel in Ecclesiastes?

Ecclesiastes insists that the good things of life—food, work, sex, wealth, honor—cannot serve as the ultimate things in life, and that if we make this mistake (as Solomon did) we will come to the end of life exhausted, frustrated, and disillusioned. Only God satisfies.

Jesus really had it all, even more than Solomon. He had unbounded wealth and honor in heaven. He had everything Solomon chased after. To an infinite degree. And he emptied himself and gave it all up and came to earth and suffered and died. Why? So that you and I, wayward sinners, can have real wealth, real riches, real honor, in the new earth, forever.

The answer really is, as we say in BYG, God'sRedemptivePlan.
