Will babies who have been aborted go directly to the Lord as members of the Church or will they be part of another population? I imagine they would be the Church, but I’d appreciate your clarification.
All aborted babies belong to the Lord and have eternal life. We know this because life begins at conception (Psalm 139:13-14) and all children below the age of accountability have eternal life (Romans 7:9).
We also know that during the Church age, the spirits of those who belong to the Lord go directly to be with Him upon death (2 Cor. 5:6-8). There they await the resurrection that will accompany the rapture. Therefore I think we can assume that babies who are aborted during the Church Age will be part of the Church.
