You must have faith in God.
Once I tried to use Him, now He uses me.
God does not so much want us to do things as to let people see what He can do.
We must never forget that Christ did not suffer just during His three years of public ministry or the last few days of His life when He was crucified. No, He suffered throughout His life on earth. He who was without sin lived daily with the corruption and sinfulness of lost humanity.
Prayer is the link that connects us with God.
Prayer is the mighty engine that is to move the missionary work.
