Bearing better fruit

My dictionary defines a "sleeper" as "someone or something unpromising or unnoticed that suddenly attains prominence or value."

Sometimes a "sleeper" is a verse you didn't notice before, and that is now overturning your life. Such as Romans 15:13: "May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit."

Another version puts it this way: "May the God of hope fill you with all joy and hope in believing, so that by the power of the Holy Spirit you may abound in hope."

I have been looking for personal "joy" and "peace" ever since I saw them in the list of fruit of the Spirit (Galatians 5:22,23) and decided that it's not normal, after thirty years, for a fruit tree to not have better fruit. It's not God's fault either. Like he said through the prophet: "What more was there to do for my vineyard, that I have not done in it?" (Isaiah 5:4).

Maybe there was something I wasn't doing. I found it in this sleeper verse. Fruit like "joy" and "peace" is all of grace, yes. But these comes only as you trust in him. They come only in believing.

I'm being very existential about this. I am experiencing joy these days as I am in this moment believing God, not as I am disbelieving God. It's really that simple --- as all of the "sleeper" verses in the Bible are.
