Where those in the second half of life stand watch, walking in the Spirit.
A sentinel is a guard, a lookout, a person keeping watch. Frequently a soldier, but not always. If you're watching a pot, waiting for it to boil, you're standing sentinel (v.) over it — and incidentally, it probably won't boil until you leave.
Etymologists think sentinel stems from the Old Italian words sentina, meaning "vigilance," and sentire, "to hear or perceive." It's a close cousin of sentry, which means the same thing. You can use sentinel as a noun or a verb. (Vocabulary.com)
- Love God, one another and others.
There is still plenty to do, sharing valuable life experiences He has given to us with the body of Christ, His people here. We also long to share and love others in our community 'at large', He leading us to make disciples of Christ who make disciples of Christ. While we may be in the second half of life, we certainly aren't ready to stop living it nor 'retire' from it! May God help us stand as His sentinels for His glory in His kingdom.
