The possessor of true religious liberty, when he has submissively and conscientiously done his duty, is not troubled by any undue anxiety in relation to the result.
It may be laid down as a maxim, that he, who asserts that he has left all things in the hands of God, and at the same time exhibits trouble and agitation of spirit in relation to the results of those very things, (with the exception of those agitated movements or disquietudes, which are purely instinctive,) gives abundant evidence, in the fact of this agitation of spirit, that he has not really made the entire surrender, which he professes to have made. The alleged facts are contradictory of each other, and both cannot exist at the same time.
