Our election is not written in particular in the word of God; but our duty is plainly set down there. If men conscientiously perform their duty, this is the way to come to the knowledge of their election. Men therefore should not question whether they be elected or not, but first believe on Christ, and endeavor diligently to work out their own salvation; and if their works be good, and their obedience true, thereby they will come to a certain knowledge that they were elected and set apart to everlasting life.
Thomas Boston
