Most everyone has heard faith described as a series of mountains and valleys. Some may have also heard people say that if you are not progressing forward in your relationship with Jesus, you're falling back.
Now, there are flaws in almost every analogy, but just work with me.
Every moment in your faith you will either climb the mountain or fall down the mountain. When I imagine a mountain top I imagine a time of relief, or of relaxation. Its a time when we stop working so hard and just enjoy. But it is also the end of an accomplishment and a time of preparation for descent. We should never consider anything over, and we should definitely never want to descend. I think that our "mountain tops" are simply the times when climbing the mountain is just so incredibly joyful because we're walking right alongside our Savior. We still have to be faithful in prayer, and consistent in study, and undeviating in obedience because that is what will bring us closer to the blissful presence of our Jesus. We have to continue to surrender and continue to learn and love and accept Him more and more so that we won't fall back down. It can be daunting looking up the mountain. It seems to never end and there are some really tough spots that look impossible to climb. But when you don't want to even start the climb, don't be overwhelmed by the whole slope. Take your first step and then take a second and then a third and a fourth, and when you can't take the fifth step, look beside you and let Jesus hold your hand.
The valleys are inevitable because of our obvious humanity. We will struggle and there will be times when we don't feel delighted or carefree, but we are trusting God because we know Him and He told us during our blissful climb that He would be with us even in the valleys.
