The word "abortion" is not found in the Bible, but it does tell 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 that close relationship 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 a person with murder on his record be right with God? God hates murder! (Exodus 20:13, Proverbs 6:16-19)
We find the answer in 2 Samuel 12. When David was confronted about his sin, he fully confessed it. He'd been covering it up, but now he admitted he'd sinned against God. David would suffer the consequences of his sin the rest of his life, but verse 13 tells us very clearly that God forgave him.
David later wrote two poems about his experience (Psalm 32 and Psalm 51). They reveal the turmoil he'd felt before confessing, and the joy he felt afterward. This can be your experience too, no matter what you've done.
The same was true of the people who crucified Jesus. In Acts 3:14-19, the Apostle Peter 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 were guilty of His death. 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."
