John 15:13 - Greater love has no one than this: to lay down one’s life for one’s friends.

Today we pause to remember, honor, and give thanks for our brothers and sisters who in the service of our freedom made the ultimate sacrifice.

All gave some, some gave all.

Never above you. Never below you. Always beside you.

Happy Memorial Weekend guys. It’s time to hit the range with the homies!”
