A rare and unusual book, recommended to me by my son. The focus is on the deeper life in Christ, being Christ in us, the hope (expectation) of glory. Saphir urges the Word, revealing Christ, the one to whom we are to deal with, and not just the word itself. Prayer is enjoined, and at the level the Bible expects and commands, without diverting attention to issues of the foreknowledge and will of God. In other words we are commanded to pray and our prayers are not to be aborted or crippled by inquiry into matters beyond our understanding. Saphir does not advocate an naive intentional suppression of inquiry, but I think is saying we should first do what God has said, and come to him and ask and he will then answer.
Saphir also deals with the Word and its impact on us, ending up much like Calvin, that we know through the power and witness of the Spirit that these words in fact come from God and are his word to us, without omission, flaw, or misdirection in life.
On a more distressing level, Saphir points out that Christ is actually in us, by and through the Spirit. As such, when we grieve the Spirit, we do not grieve the Spirit externally, but the Spirit within. If we are sensitive to this, it gives us more reason to please the Spirit, resident in us.
Saphir writes from a time long gone, in one sense. However, what he says and advocates ties to the Word, and to prior Christian experience, across time and cultures, and therefore serves as an encouragement to us all.
