All study should build a deeper relationship with Jesus. The below list is by no means an exhaustive list, but intended to share some research that others have found helpful.
John 14:26 "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.”
