The Tree of Life, and Q&A

On today’s Bible Answer Man broadcast (03/29/23), Hank compares the tree of life in the Garden of Eden—which was barred because of sin—with the tree of life we see again in the book of Revelation. Hank explains that Jesus died upon a tree that gives eternal life, thus making a way from paradise lost to paradise restored. Hank also answers the following questions: Once you become a Christian, how does the Law apply to you? How will we view sin in heaven? What existed before God created the earth? I have been wrestling with certain passages of Scripture brought up by some of my Reformed friends. What is your interpretation of John 6:64-65 and Romans chapter 9? How should we understand the Trinity in light of Deuteronomy 6:4 and John 10:30? Are these passages referring to God being one in quantity or quality?
