because it is written, "You shall be holy; for I am holy."
 It will be observed here that there are two motives to holiness: the first is that He has called us; the next, that we call Him, and this by the sweet and near title of Father. It is no longer relationship with and recognition of a God that rules and governs. This was known in Israel, but it could in no wise draw out the affections in the same way as calling Him Father. We are told and meant to know, that as He called us by His grace, so we should call on Him as Father. It is after the pattern, not of a subject with a sovereign, but of a child's dependence on a parent. To this double motive there is added another consideration on which it all rests, and without which neither of these things could be. How is it that He has been pleased thus to call us? and how is it that we can call Him Father? The answer is this: "Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; but with the precious blood of Christ." The Jews were all familiar with a ransom price that used to be paid in silver. But it did not matter whether one gave silver or gold, it was all corruptible; and to what did it come at last? The precious blood of Christ is another thing altogether; and there alone is efficacy found before God; so also His incorruptible seed revealing Himself is planted in the heart of the saint.
