Baptism for your crises of faith

Therefore I say, if you did not believe then believe now and say thus: The baptism indeed was right, but I, alas! did not receive it aright. For I myself also, and all who are baptized, must speak thus before God: I come hither in my faith and in that of others, yet I cannot rest in this, that I believe, and that many people pray for me; but in this I rest, that it is Thy Word and command. Just as I go to the Sacrament trusting not in my faith, but in the Word of Christ; whether I am strong or weak, that I commit to God. But this I know, that He bids me go, eat and drink, etc., and gives me His body and blood; that will not deceive me or prove false to me.
