“Daily devotional” is a phrase used to describe having a daily time of Bible reading and instruction. It could include reading a commentary or Bible notes or listening to a Bible reading and sermon on podcast.
It's really important to spend time with God daily. “For God, who said, ‘Let light shine out of darkness,’ made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ” 2 Corinthians 4:6). A wise man once said “The gospel brings man to God; daily devotions keep him close to God.” Echoing the Scripture: “Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded” (James 4:8).
