To follow up on the previous post, I wanted to share a concept I hadn't considered until I was asked.
What if your greatest failure is yet to happen?
This question isn't to cause you to live in fear, but to warn you, we could all falter at anytime. If you study the Bible long, you'll see those who failed the greatest often thought they were doing the right thing. Eve, Jacob, Saul, Judas, Saul/Paul, to name a few, all thought they knew best, some God redeemed, others He did not.
It's a warning to keep you on your knees, seeking God's grace to live for Him, to understand His Scripture that you are studying diligently.
When I look at my past, I couldn't imagine my greatest failure to be future, I've messed up so much. But there's a chance, even greater if I become confident in myself, slack off in my pursuit of God and His word and lose the awe I have of Jesus. This is where having fellow Christians that you live in community with are helpful to pull you back on track if they see you going astray.
Take warning, love God, humble yourself before Him.
