Our faith can be like a sidewalk path. Have you ever been on a bike path or a long hiking trail. Whether it is with pavement or not I think you might find the analogy in this post.
Bike paths and trails can go for miles in length. Even if we know how long the trail is suppose to be, it can seem like a long, never-ending journey. Sometimes life seems like a never-ending journey too but just as trails only go so far, such life also eventually ends.
When I go for runs or bike rides, the hardest parts of the ride is the steep up-hill slopes. Fortunately (just as the old saying goes "everything that goes up must come down") holds true and I find a lot of relief and fun in my exercise journeys when I find it still holds true.
Life has its ups and its downs too. There will highlights and beautiful times in our life, but do not forget about the downs. God uses those times too!
Finally another interesting similarity is in the width. Bike paths and hiking trails are sometimes a foot wide (maybe two feet) or less. Width can be illustrated as our stance on life...how we handle it. If we are handling life too critically and fall off of the path to the right into the weeds and thorns or not caring enough and falling off of the path to the left. Being too liberal and too nice for your own good or being too hard on yourself or too conservative. How we handle life is almost as or more important than making it to the end.
All of us desire comfort and love and stability in all aspects of our life. We need to be social and close to God. Imagine the direct middle of a bike path, it is a comfortable place to be as there is room on both sides of you to be free yet you are loved and you are stable and safe.
God's love for us, his life for us is somewhere in there. He doesn't want us to be larking around the edges and about to fall off. He wants to guide us to His glory and His will. His good, perfect, and pleasing will. The one that is the straight and narrow way. Sidewalks are kind of narrow (compared to its surroundings usually).
Anyways I hope I have left you with some thoughts to think about, some imagination to be added to this post and bounce some more ideas around.
