Christians, our minds and our constitutions must be strong in our day and age. We must build a strong mind and a persevering constitution to endure the trials and persecution coming ahead. Mental work is hard work because it is easy to live undisciplined lives, and Christians do not want to face the enemies schemes in the strength of the Lord’s might. We need to sharpen our minds with God’s word and run the mental marathon. We are in a battle and we are being attacked. We must stand firm as the promises of God in sacred scripture hold us up.
