In making a consecration to God in the manner which has been indicated, we take a step, which, considered in any point of view, may be regarded as absolutely necessary. It is not enough, however, to offer all. In the same spirit of reliance on God, we must also BELIEVE THAT ALL IS ACCEPTED.
It is the belief that God is faithful to his word; and that, in accordance with his word, he will receive and does now receive all that unreservedly lay themselves upon his altar, which seems especially to secure the presence of a sanctifying efficacy. On the contrary, he who consecrates himself to God, however sincere he may be in the act of consecration, but who greatly dishonors the veracity of God by remaining without the faith of ACCEPTANCE, deprives himself of that mighty power, which faith alone is capable of imparting, and necessarily lies prostrate and exposed to all the dreadful attacks of the adversary.
