In primary we are singing a song about walking with Jesus. If we are walking with Jesus and holding His hand, He can strengthen us to do all things that are right and good even if they are seemingly impossible to do. As a friend in college once told me, "It is amazing what two people can do when one of them is God."
Just as children walk holding their parents hand for safety in a parking lot or crossing a street, We need to have the humility of a child to understand we cannot see all the dangers around us or protect ourselves from every threat. Some tasks we are required to perform ARE more than we can do. God does sometimes give us trial, tests, or tasks that ARE more than we can handle - at least more than we can handle ALONE.
He wants us to depend on Him. He wants us to know that is by Him that we are led, by Him that we are saved, and through Him that we can be made perfect. He does not want us to be independent of Him. He wants us to Come unto Him and to know Him and that through Him and with Him, we can do all things.
So how will you take the Savior's outstretched hand today? How will you walk with Him?
