Answer. We may know it by knowing that we have met all the conditions. This grace is obtained upon the conditions of consecration and faith. When we are sure that we have measured up to a true Bible consecration, we will have no difficulty in knowing that we are sanctified. The depth of meaning of this consecration does not necessarily need to be fully comprehended by the seeker, as we enter into this covenant, but there is a yielding up of ourself and entire all, to the known and unknown will of God, to an extent that covers everything. God knows when we have reached and passed this point, and it will not be long before the Holy Spirit will definitely witness to us that the consecration is complete, and the covenant ratified by this glorious indwelling consciousness. This consecration may be illustrated by the contract and union of holy matrimony. When the bride and groom enter into the covenant according to God's word, they have little knowledge of the obligations they are taking upon themselves. They know nothing of the detailed realities of life; its joys and sorrows, hardships and trials that are before them; but they know that they dearly love each other, and have not the slightest fear in yielding themselves to each other completely and exclusively, so long as they both shall live. They enter into this covenant with all good confidence that the object of their love will not require anything hard or impossible, and as the future realities of life unfold and one by one they meet the many responsibilities that the covenant implies, they find that their love is equal to the responsibility, and as long as they continue to love each other they will never have the slightest disposition to break that marriage covenant. So the heart which makes the consecration for sanctification will not comprehend the great scope of its meaning at the time of entering into this covenant, but if we love Jesus as we should we will not fear what he may require of us in the details of his will in the future. We are already enraptured with his love. He has proved himself to be a loving and faithful Redeemer in dying for us, and now as we see he requires us to yield ourselves even to death for him, we can confidently enter into the conditions of this covenant with the assurance that he will demand nothing of us beyond the power of the love to fulfill. Yes, we will know definitely when our consecration is complete, and then we will have no trouble to believe in the promises for the cleansing. As Bible repentance is the believing ground for justification, so Bible consecration is the believing ground for sanctification. Ques. How may we keep sanctified?
