Paul admonishes us to examine ourselves to see whether we have true faith (2 Cor. 13:5). The blessings we see in our lives are by themselves not sufficient proof that we belong to God. After all, Esau was blessed and was yet shown to lack faith. True devotion to Christ is shown in our repentance for sin, the fruit we have in our life, and our faithfulness in the task the Lord has given us. That is, we must seek first the kingdom of God and His righteousness (Matt. 6:33).
