Birds have to flap their wings in order to take off in flight. A space rocket must also put out tremendous power in order to break away from gravity. Every true work of God is going to take a lot of effort in the beginning, and will seemingly be impossible except with the LORD’s help. The bird never stops flapping until it catches a strong breeze which will take it where it needs to go. The space rocket will get past the pull of gravity to where its rockets can just be used occasionally to correct orbit or direction. There is a time with God that things will get easier, and more comfortable, and when your confidence in your own ability to keep going rises, you will probably be given another assignment, which is harder than the last one. Just flap your wings!
