10 “In tribulation you called on Me, and I delivered you”. Let each Christian conscience recognise itself, if it have devoutly passed the Red Sea, if with faith in believing and observing it has heard a strange language which it knew not, let it recognise itself as having been heard in its tribulation. For that was a great tribulation, to be weighed down with loads of sins. How does the conscience, lifted from the earth, rejoice. Lo, you are baptized, your conscience which was yesterday overladen, today rejoices you. You have been heard in tribulation, remember your tribulation. Before you came to the water, what anxiety did you bear on you! What fastings did you practise! What tribulations did you carry in your heart! What inward, pious, devout prayers! Slain are your enemies; all your sins are blotted out. In tribulation you called upon Me, and I delivered you.
