I lost my son in a car wreck 5 years ago. He was a Christian. I offer prayers for his soul. Should I do this?
If your son was a Christian when he died he left his body behind and went straight to be with the Lord at that time (Phil. 1:21-23). Now the only thing he needs to make his eternity complete is his new body, which he will receive at the time of the rapture (1 Thes. 4:16-7). There is no need for you to pray for him anymore.
