8 For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ.
2 Peter 1:8
Peter gives the positive and negative to possessing the previous qualities.
None of us want to be ineffective in our lives, nor in our knowledge of Christ. We all want to contribute to the Kingdom and ministries around the world.
The solution, then, is straight forward, though not simple: read and apply the qualities mentioned to our lives.
We should be able to say a year from now, I had more faith, goodness, understanding, self control, perseverance, godliness, mutual affection and love than I did last year at this time. By how much? That’s not the point. The point is that we’re increasing in these qualities and not going stagnant or decreasing in those qualities.
