“you can’t take it with you..”
Actually, from what I can tell the fruits of obedience to the Holy Spirit (the rewards for the works that can pass through the fire) we can take.
But here I need to point out that what Paul called the body of death apparently is perfectly willing to ape the activities and the fruit of the Spirit if that means we are still obeying it as very moral people rather that obeying the Holy Spirit. There’s an old story about a young preacher to illustrate this: a young visiting preacher got up before a congregation and preached his heart out ... but despite his expectations the invitation went unheeded and people just sort of were polite but not too friendly after services. Concerned he turned to an old country preacher who was also visiting to ask what he’d done wrong. The old guy nodded thoughtfully before saying: “Let me ask you, son, were you sent or did you just went?”
How many people go in their own strength and their own wisdom rather than from obedience? These, I’m persuaded, are the works that cannot endure even though the people themselves will be saved because of Grace.
