The Bible does suggest that those who've entered heaven before us actually may know what is happening on earth. After listing the great heroes of the faith who are now in heaven, the writer to the Hebrews then adds, "Therefore since we are surrounded by such a great cloud of witnesses... let us run with perseverance the race marked out for us" (Hebrews 12:1).
Although it's interesting to speculate about this, one fact is certain: God knows what is happening in our life -- and in the life of every person on earth. God is all-knowing, and nothing -- absolutely nothing -- can be hidden from Him. Not only does He know what we do (or fail to do), but He also knows why. The Bible says, "Nothing in all creation is hidden from God's sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account" (Hebrews 4:13).
Does that make you nervous? Perhaps it does, because you and I know what goes on in our hearts, and we know we aren't perfect. But the Bible tells us an even greater truth: God loves us, and He wants to forgive us and cleanse us from all our sins. This is why Jesus Christ came into the world: To save us from our sins.
Be grateful for the hope we have of being reunited with those who have already entered heaven. And make sure of your eternal destiny by giving your life to Jesus Christ today.
