A college basketball player expecting to be drafted into professional basketball has about the same chance as winning the lottery, less than 1%. Our calling is even chancier. God personally picked each of us out of billions of people, picking the weak, the base, and the foolish to put the wise, mighty, and the noble to shame. God specifically chooses those He wants to be part of Christ's Body according to his purpose. It is a holy calling according to His purpose and grace; we had nothing to do with it. We are admonished to make our calling sure; God promises to do His part, but we have to do ours, growing spiritually and bearing fruit, systematically climbing the ladder of virtues outlined in II Peter. We are to be abounding in these virtues; with the power of God, we can attain this. If we follow these steps diligently, we will attain the Kingdom of God. None of this striving toward the Kingdom as a part of His family would have been possible without His calling us.
