There will be no language barriers and no cultural differences. For the very first time we will love each other like God loves us. We will love being together. We all will fall on our faces and thank God that He was so patient and forgiving of us when on earth we were so concerned about our differences. And in our heavenly love for each other, for Christ, and for God will be seen God's greatest miracle.
Human beings have so many problems.
We will get to Heaven and not have these problems. There are some people who don't like me. There are some people that are hard for me to like. Becoming a Christian is letting God change you. The more He changes you, the more people there are that you like.
