RE: “The ultimate purpose of stewardship is for all people to come to the knowledge of the truth of God revealed in Jesus Christ and be saved.”

It seems to me that being saved would be "ultimate" if nothing else is to come of it or come after it. But that’s not what Scripture tells us. God saved us for these purposes:

— that we “might walk in newness of life … dead to sin and alive to God in Christ Jesus” (Romans 6:5,11 ESV).
— “for good works, which God prepared beforehand, that we should walk in them” (Eph. 2:10 ESV).
— “that those who live might no longer live for themselves but for him who for their sake died and was raised” (2 Cor 5:15 ESV).
— “to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works” (Titus 2:14 ESV).
— that the Father may be glorified by our fruitfulness (John 15:8 ESV).
— “that my joy may be in you, and that your joy may be full”(John 15:11 ESV), said Jesus.
— “that you may proclaim the excellencies of him who called you out of darkness into his marvelous light” (1 Peter 2:9 ESV).
— “to the praise of his glorious grace,” “to the praise of his glory,” and again, “to the praise of his glory” (Eph. 1:6,12,14 ESV)!
