Paul shows us how God, as a loving father, has given us tutors and guides through the Law but that they are not the destination – only a means to an end. That end is trust; trusting God to provide and keep His Promise given to Abraham which was fulfilled through Jesus.

In chapter 3, Paul breaks down the purpose of the Law and that it was preceded with faith – to trust in God – first. Following contract law, the law which came 430 years later could not modify that earlier agreement. He then deals with the struggle for identity that the only thing we need is to trust in Jesus as our identity, nothing more.
