Related to meletaō (to care for, to practice). Denotes careful attention, diligent care, or concern. The concept of giving proper attention and diligence to spiritual matters.
The Scriptures repeatedly call believers to diligent attention to spiritual truth. 'Give attention to reading, to exhortation, to teaching' (1 Timothy 4:13). 'Be diligent to present yourself approved to God' (2 Timothy 2:15). Christianity is not casual — it demands the focused care of a farmer tending crops, a soldier on duty, and an athlete in training.
