Sin’s Role To understand why Jesus had to die we must understand a little of what sin is and the nature of God. We will summarize these two issues to place this question within a proper context.
God is a relational God who is by nature perfectly holy (Isaiah 54:5 and Revelation 4:8) and absolutely just (Revelation 16:5). Scripture says, “He is the Rock; his deeds are perfect. Everything he does is just and fair” (Deuteronomy 32:4). Doing holy and just things isn’t something God decides to do, it is something he is. He by nature is holy and just.
