Jesus has called us as believers to bear fruit for his glory. We are expected to be effective and productive in our witness of him in this world. But bearing fruit and being effective requires a deep commitment and being intentional. It doesn’t just “happen” without effort, discipline and focus on growing in the very character traits Peter highlights above.
If anything is needed in our lives and culture today it is likewise men and women of Christ-like character. This is in fact God’s one and only purpose for our lives as Christians, that we become like Jesus. Further, when I consider my biggest regrets in life and ministry, they all revolve around a breakdown in walking in godly character.
But God has one purpose for my life and yours and every other Christian in every other generation and every generation to come, until Christ comes back and we are perfected. It is a singular purpose that is the same for every one of us.
