The Bible tells us about a man who probably could relate very well to women who've aborted their children, or to anyone who's participated in an abortion. His name was David.
2 Samuel 11 records how David lusted after another man's wife. He committed adultery with her, got her pregnant, and abused his kingly authority by having her husband killed so he could marry her. Earlier in his life David had been called "a man after God's own heart" (1 Sam. 13:14), but now their close fellowship was broken.
If we were to jump ahead to long after David was dead and buried, we'd find he became the standard by which other kings of Israel were judged. Except for killing an innocent man and taking his wife, it was said he "did right in the eyes of the Lord" (1 Kings 15:5). How could this be true for a person with murder on his conscience?
We find the answer in 2 Samuel 12. It tells how David was confronted with his sin, and how he finally confessed it. We learn he would suffer consequences of his sin, but also that God forgave him.
David later wrote two poems about his experience (Psalm 32 and Psalm 51). They expressed the turmoil he'd felt before confessing, and the joy he experienced afterward.
This can be your experience too, no matter what you've done. Consider what Peter told the people who crucified Jesus. In Acts 3:14-19 he accused them of killing the One who'd come to give life...of condemning to death the only One who'd never sinned...of demanding a killer go free in His place. They'd acted in ignorance, but that was no excuse.
What now? Were they forever guilty? The worst people who'd ever lived?
No! Even they could be saved from sin and death. Peter told them to "repent and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord."
That was good news for them back then, and great news for all of us today. What should you do? Isaiah 55:6-7 says,
Seek the Lord while He may be found;
call on Him while He is near.
Let the wicked forsake their ways
and the unrighteous their thoughts.
Let them turn to the Lord, and He will have mercy on them,
and to our God, for He will freely pardon.
