The soothing words of comfort from Christ from the opening verse in this chapter is what every believer needs:
Do not let your heart be troubled (afraid, cowardly). Believe [confidently] in God and trust in Him...
Though troubling times and situations shall come, we must be conscious to find peace with the Lord.
Though the way things go may breed worries, we are admonished not to be troubled. He went ahead to justify this words of comfort by telling us the better home prepaid for us. The hope of reaching the better place should give us peace.
More endearingly is that the way to the better place is through Him (Christ). He is also the life we need to access that better place and in Him we have all the truths that bring joys to our hearts.
