Chemnitz on Receptive Spirituality

God does not confer and convey grace in this life just once, so that it is at once complete and perfect, so that as long as we are in this life God would will and convey nothing more, and that a person would need to receive nothing more from God; but God is always giving and man is always receiving, in order that we may be joined more and more fully and perfectly to Christ, and may hold the forgiveness of sins or reconciliation more firmly, so that the benefits of redemption, which have been begun in us, may be preserved and strengthened and may grow and increase.  - Examen II:76,77.
