An obvious fact you come to embrace as you get older is that you will never get this moment back. We know it to be true on an intellectual level all our lives, but only the passing years allow it to come to relevance. This has profound implications not only in our physical lives but even more so in our spiritual growth.
Each moment is our one shot to maximize it for His glory. Every moment we decide to live for God or live for ourselves. His Word tells us we will have to give an account for every idle word and, by implication, every thoughtless moment. (Matthew 12:36; 2 Corinthians 5:10) We can’t live life on autopilot and expect to receive the reward of eternity with Christ.
