One who doubteth of his being in Christ, or of his due preparation to the sacrament of the Lord’ s supper, may have true interest in Christ, though he be not yet assured thereof;1 and in God’ s account hath it, if he be duly affected with the apprehension of the want of it,2 and unfeignedly desires to be found in Christ,3 and to depart from iniquity:4 in which case (because promises are made, and this sacrament is appointed, for the relief even of weak and doubting Christians5 ) he is to bewail his unbelief,6 and labor to have his doubts resolved;7 and, so doing, he may and ought to come to the Lord’ s supper, that he may be further strengthened.8
