The best question is not why we confess what we did, but why did we do the thing, that causes the hurt.
Confession does not hurt, it is true confession that saves us, but what hurts is the thing we did, that needed confession.
If we did actions without any trouble in our conscience, and afterwards regret what we did, that is guilt.
But it is not guilt for confession, it is guilt for anything wrong that we did. Confession can damage a marriage we have for ourselves, but a marriage we have with God, is looking forward to what Jesus showed us, that they that be married, be as though they were not. ( marriage is temporary, in this life only.) and how we are married to another, to Christ, who betrothed us to Him in faithfulness.
Matthew 22:29 Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.
30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
1 Corinthians 7:29 But this I say, brethren, the time is short: it remaineth, that both they that have wives be as though they had none;
30 And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not;
31 And they that use this world, as not abusing it: for the fashion of this world passeth away.
Hosea 2:19 And I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in judgment, and in lovingkindness, and in mercies.
20 I will even betroth thee unto me in faithfulness: and thou shalt know the Lord.
Romans 7:4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be
married to
another, even to him who is raised from the dead, that we should bring forth fruit unto God.
1 Corinthians 6:16 What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh.
17 But he that is joined unto the Lord is one spirit.
