Honestly, I have mixed feelings about the types of people that fill the Bible. Lowly shepherds like David. Simple fishermen like Peter. Hated tax collectors like Zacchaeus. Men like Moses, who didn't speak eloquently.
When I was younger, I thought that God should have chosen more powerful and worldly people to serve Him. That was because I didn't yet understand how God uses every day people, like you and me with our faults and foibles, to do amazing things.
Sometimes they are little but amazing things like lending a needed hand to a neighbor to make her day a little brighter. Other times, they are huge amazing things like freeing a nation or curing polio. Most of the time, though, we make a difference doing things that fall in the middle.
But, whatever the size of our impact, we can be sure that we do have a purpose for our lives. If we listen as God speaks to us and understand His will for us, through Him we can do amazing things that make a difference.
Why don't you take a moment right now and ask God how you can make a difference?
