“I have committed _____. Will God ever forgive me?”
I think I can safely say yes. As individual acts go, there is absolutely nothing you have ever done that our Lord will not forgive, assuming your repentance and desire for his forgiveness is genuine. We could fill in that blank space above with any sin, crime or misdemeanor, however heinous or grossly offensive to the Almighty. That is my personal belief on the authority of the word of God.
Let me argue that point for any among our readers who may disagree.
