Exodus 23:30 By little and little I will drive them out from before thee, until thou be increased, and inherit the land.
It is always little by little that God will do the ministry. If he does too much too quick we could never deal with the success and never keep up with the work.
We have to grow with our responsibilities. Just do your job to the best of your ability every day. Try to stretch yourself all that you can and you will see what God can do with you
It is always little by little by little that we grow and have success in the ministry or our lives for various reasons.
