There's an interesting verse in 2 Timothy 1:14 that says, “Guard the good deposit that was entrusted to you—guard it with the help of the Holy Spirit who lives in us.” When I was in seminary, we were taught that the deposit is “true doctrine”; it's making sure that scripture is sound. Verse 13 leading into verse 14 says, “What you have heard from me, keep as the pattern of sound teaching…Guard the good deposit…” So, there's a sense that this good deposit is the gospel. It’s right theology. It's what you believe. It's not polluting or diluting or ignoring this deposit of good, solid theology.
But I think there's something more to this deposit. I think God deposits his Holy Spirit in a unique way into each one of us, which is perfectly crafted for us. He takes into consideration our station in life, our maturity in Christ, our giftedness, and our abilities and skills. God deposits the Holy Spirit inside of us to become the landscape for all good things from the Lord to grow from. We have to guard that deposit because we can pollute it so quickly. We can begin to rely on our own skills and talents and God says, “I've given you a deposit. Live within that deposit because there's life in there.”
So, the question becomes, what is the deposit that God has placed in us? What is it that's unique to us? What is our unique mantle that we hold on our shoulders? I believe without a doubt that a clear understanding of scripture, as scripture speaks for itself, is part of this deposit. But I think the deposit also includes the giftedness that God has given to us. We need to express our faith within that giftedness. There are times when I know that what I'm deciding is not out of the good deposit, it's out of what is around the good deposit; everything that I think I can do without the Holy Spirit. So, that's why I think Paul says to Timothy, “Guard it with the help of the Holy Spirit who lives inside us.” My admonition for those who are readers of this blog is: guard the good deposit.
