Bulrushes, slime and pitch. Those aren’t the components you would think would be needed to make a life saving device. But those are the exact things that were available to Moses’ mother. She was able to use those materials to make the ark that baby Moses floated in down the river to safety.
Sometimes we get bogged down thinking “if only I had this then I would be better off”. Look at what you do have. If God has called you to it then He’s provided you with the necessary resources you need to get going.
You may have to get creative like Moses’ momma did. You’ll definitely have to trust that Jesus can bless it. But by having the desire to succeed, the willingness to work for it and trust in God you will be successful. So stop wishful thinking, take what The Lord has given you and get to work.
