Let’s not confuse three separate issues:
We must always be willing to allow for forgiveness of sins. Forgiveness is ultimately between the woman and God. He forgave Saul (Paul) who was guilty of putting many Christians to death so His capacity to forgive those who truly repent is quite vast. We should be equally willing.
There are still consequences to sin and one of those may be a lasting feeling of guilt over taking the life of a child and the knowledge that this can never be undone. Another consequence may be the shunning by friends and family members. I would not say that such shunning is judging, any more than a parent would willingly allow their children access to a repentant sex offender. We should, however, have compassion for those who admit that their actions were wrong.
The third issue is societal. Abortion should still be strongly condemned and we should not stop speaking out against abortion simply because some will feel “judged”. That is often the Holy Spirit at work pricking the conscience of one who needs repentance.
Amen.
