Yes, all Christians in the US Military and in the US Pentagon must personally swear allegiance to Jesus Christ the King in celebration of Easter.
No one needs to see you make your alleagiance.
Christ sees all, and you can swear allegiance to Christ in the privacy of your home, when you are alone.
But it is important for you to take this proactive dedication to Christ the Risen King.
If you die on the battle field, you will stand before Jesus Christ, who is the Awesome Judge.
He knows your heart and whether you swore allegiance to Him or not.
Do you want to take your chance with your eternity?
