What does the Bible mean by being renewed day by day?

The concept of being renewed day by day speaks to the continuous work of the Holy Spirit in the life of the believer. 2 Corinthians 4:16 articulates that while our outer self is wasting away, our inner self is being renewed. This renewal is essential for facing the trials and tribulations of life. Believers are called to seek daily sustenance from God, as reflected in the petition for daily bread in the Lord's Prayer. This daily dependence cultivates a relationship where we consciously rely upon Christ—the 'manna from heaven'—to nourish our souls and empower us for the journey ahead.
