Jesus said we could do big things if we only had faith the size of a mustard seed. A pile of dirt can be moved with one pass of a dozer. The same pile can be moved with a shovel . . . it just takes longer.
Jesus' faith was like a dozer - ours more like a shovel. Too often we give up on the things we pray for because they don't happen quickly. You can have miraculous faith, just as Jesus said . . . if you're willing to take it one shovel at a time.
There is also personal faith. God has told us that he loves us for example. Satan tells us that he doesn't - that it's conditional. It can be believable at times. God is pleased when we can hold to what he told us. It is a process. I call it, The Fight of Faith.
