I think if you asked your average man-on-the-street Christian if all sins are equal to God, most would say, “Yes.” But Stand To Reason takes a look at the question and says, “Not so fast, monsignor”:
…the Bible makes it clear that not all sins are considered equal by God. This is actually made clear from Jesus’ own teaching. First, Jesus testifies that there are greater sins (and, by extension, lesser sins). Standing before Pontius Pilate, Jesus says, “You would have no authority over me at all unless it had been given you from above. Therefore he who delivered me over to you has the greater sin” (John 19:11). Not only does God regard some sins as greater and some lesser, but Jesus tells us that there is a greatest sin. Jesus states, “whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come” (Matt. 12:32b).
