I agree on the consequence of sin, but if that person in prison is in Christ, to me they still go to heaven; repented for or not. There are many sins that cause condemnation and remorse we need not enter into, and 1 Jn 1:7 says "But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." In other words. We do needs be subject as we read in Eph 5:24 & Eph 5:26, "That he might sanctify and cleanse it with the washing of water by the word." The depth of our love is established directly by following after the Spirit instead of the flesh, and our peace and reward proportional to that separation.
