My cousin passed away recently. She was 64 and mentally handicapped since the age of 5. I always called her one of Jesus special little children because she loved to color and play with stuffed animals. When she goes before Jesus will she appear as a child from when she lost her mental abilities at 5? Or will she appear as a fully functioning adult? Are people like her protected under the blood of Jesus? I know she loved Him because she has told us so.
According to Romans 7:9 all children belong to God and have eternal life until they become intellectually mature enough to understand the nature and consequences of sin. At that point they must be born again to be saved from the penalty of their sins . If a person never achieves sufficient intellectual maturity to comprehend these things, he or she will always belong to God and will have eternal life.
As to how your cousin will appear in the next life, the Bible does not provide any details on our appearance after the rapture/resurrection. 1 John 3:2 says what we will be has not yet been made known. In speaking of the resurrection, Paul said we’ll be like the flower that blooms. It doesn’t look anything like the seed we planted, but we recognize it because we know the seed it came from (1 Cor. 15:37-38).
