In essence, a sin is a sin - sexual or otherwise. Sins have to be dealt with.
They have to be acknowledged, repented and placed under the blood of the Lamb who was slain on our behalf.
Even if they/we will go on to sin again - at this point of healing, there must be genuine intent to sin no more.
Those who truly repent - and who do not personally select which sins they consider to be right or wrong - these alone will walk with the Saviour.
False or partial repentance - especially that based on the opinions of Man - is surely an abomination.
Without repentance, Hell is the ultimate and inevitable destination.
Perhaps Christians should not bother to warn the unseeing lost that they are lost.
Alternatively, believers could take the Great Commission seriously and CARE that the unsaved are just drifting into a lost eternity!
