It is often argued that we all sin and that it is therefore unfair to single out homosexuals. If sinners cannot be saved, then none of us can. And how can we stand in judgement of homosexuals?
It is true that we all sin.
1 John 1:8
If we claim to be without sin, we deceive ourselves and the truth is not in us.
But notice how that passage continues.
1 John 1:9
If we confess our sins, He is faithful and just and will forgive us our sins and purify us from all unrighteousness.
We do all sin but God doesn’t intend us to sin. In fact, He has given Christians the power to not sin. Christians are no longer slaves to sin. Read Romans 6 and 7. Paul is shocked at the suggestion that Christians might carry on sinning (Romans 6:1-2).
There is no excuse for sinning. We have been given a new life in which we are free from the power of sin. However, in our weakness, we often do sin.
Christians who sin will be horrified at themselves and will humbly seek God’s forgiveness yet again. It is not warranted (because God has promised to forgive the repentant) but the Christian might even worry that he/she has irretrievably damaged his/her relationship with God.
In other words, Christians do not continue sinning and justify it or feel good about it. They are remorseful and repentant. There is a huge difference between the person who fails and deeply regrets it and the person who sins defiantly and carelessly.
It is possible that a genuinely Christian homosexual slips back into sin. But if he/she is genuinely remorseful, forgiveness will again be granted and his/her salvation not compromised.
The key question is: is the sinner repentant or defiant?
