We ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body, for we were saved in this hope.
Trials in a believer’s life increase his anticipation for heaven. Just as trials create a growing disinterest in the passing world, they also create a greater desire, for example, to be reunited with a loved one who has gone to be with the Lord. If the most beloved people in your life have entered into the presence of our precious Savior, and if you have invested your time and money in eternal things, then you won’t have much tying you to this passing world.
Beyond this life of suffering is a glorious future for the believer that makes us all the more desirous for the fulfillment of salvation. Thus trials give us a greater affection for that which is eternal—they help us long for the eternal city of heaven.
