Revelations 21:4
4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
One day we will walk with God. We will stand in the presence of our created. We will never hurt again. We will be reunited with those who have gone before. We will never have to say goodbye again. Children like my son will never have to have heart surgery again. God will wipe our tears away and welcome us home. That is what we are working for. The day we never have to fill pain and the day we will not even remember pain. I encourage you that whenever life gets hard, keep you eye on the goal we are working for. We may get rewarded by God in this life for the work we do, but nothing will ever compare to that day when I see him and bow before my Almighty God. What a wonderful day that will be.
