It is not enough to begin to pray, nor to pray aright; nor is it enough to continue for a time to pray; but we must patiently, believingly, continue in prayer until we obtain an answer; and further we have not only to continue in prayer unto the end, but we have also to believe that God does hear us, and will answer our prayers. Most frequently we fail in not continuing in prayer until the blessing is obtained, and in not expecting the blessing.
