Keeping an eternal perspective helps us face the challenges of life because it reminds us that this life is temporary and this is not our home. We are only here for a little while so let's not get so caught up in the things that won't matter in the end. Keeping an eternal perspective will also help us overcome our fears and not let our fears stop us when we remember it's all temporary anyway. There is nothing to be so afraid of other than not doing what we are here to do!
