For if we have been united with him in a death like his, we will certainly be united with him in a resurrection like his. Romans 6:5
Do we know people who have love that endures, that when one passes from this life the other follows soon after. In some instances they are united to the point of death. So it also in life, when they are united, their life with each other is a joy. Nothing is too small for these couples to accomplish when it is done in love. Some even write of their love, how they would die for the other, how they would do anything for them. It's beautiful when people love each other like this.
When we love like this we have the capacity to love God just as deeply. When we love God this way, we die of ourselves, of our selfishness. It is then that all we do is for the one we love. That is why Jesus emptied himself on the cross, his love for God and us was that great. This is not only his resurrection but ours too.
It is the same when we are united with God, we are with him in a death like his, but most assuredly we will be united with him in a ressurection like his.
