This journey into faith starts with enough faith to move a grain of sand, because we need to start off small. Just as our Spiritual walk starts with hearing and reading God's word, before we ever take that first step of faith. God understands that there is a process to growing in faith. Our faith in Him, like the mustard seed, starts off as a small thing, before we can move mountains, we need to first be able to move a grain of sand.
One of my favorite movies, illustrates this. "Karate Kid" has an instructor called Mr. Miagi, who teaches karate in a most unusual way. Much like God, Mr. Miagi, starts off the teaching karate with simple everyday chores and the student never realizes that the karate lessons have already started. The lessons are learned by following simple instructions. Washing and waxing a car, painting a fence, painting siding all become a lesson in another karate discipline. The student learns important lessons, by simply following directions.
In much the same way, our Heavenly Father teaches us life lessons, without us realizing that we are learning. Every trial, every testing, regardless of whether we fail or succeed is an important life lesson, preparing us for whatever God has in store for us, as His servants. Our faith in Him grows with every grain of sand we move through faith. we grow from moving sand, to pebbles, to rocks, to boulders, to where soon we are moving hills and mountains. As our faith grows and matures, we become powerful weapons in God's arsenal against Satan and his demon army.
As we progress in growing our faith, it is important that we teach others, lessons that we have learned. One of our first lessons was taught by Jesus to His disciples in a prayer. After Jesus praised His Father and gave God all glory and honor, Jesus taught His disciples to ask God for the simplest of sustenance, bread. Jesus realized that our growth starts with simple faith.
Billie Sunday, Billie Graham, started their ministries, the same way all of us start. Becoming a Christian and sharing our new life with one other person. God's greatest outreach is still one person at a time. God created compound interest long before a mathematician, one person teaching another, those two teaching two others, and so on. The idea is to help others grow their faith, as you grow yours.
Just as we are told to love each other, as much as we love ourselves. We can only help others achieve the level of faith we have attained. Help someone else learn to move that grain of sand. Help someone else attain your level of faith and then grow together in faith.
