Christ will lead you into many situations that will seem impossible, but don’t try to avoid them. Stay in the middle of them, for that is where you will experience God. The key difference between what appears to be impossible to us and what is actually possible is a word from our Master! Faith accepts His divine command and steps out in a direction that only God can complete. If you only attempt things that you know are possible with the visible resources you possess, those around you will not see God at work. You will be the one who receives the credit for a job well done, but God will have no part in it.
What strikes me in this devotional is that too often we work within the limits of our resources. We let budgets and finances dictate the vision instead of the other way around. I remember an old treasurer we had in the first church of which I was a member. whenever anyone asked if we could afford to do something his reply was always the same, "If you give, we can do it." Now at first thought that sounds rather narrow, but there is something of Blackaby's point in there too. Because if we believe that God is calling us to a particular ministry, then why would we doubt that he would provide the resources, and that he might call on us to be the providers of the resources needed.
Maybe the point of the feeding of the 5,000 (the subject for this devotional) for us today is that we need to put all our available resources into God's hands and let him do the miracle of multiplication.
Now I wonder where that train of thought is heading?
