I have to respectfully disagree with your position about closing the prayer in "Jesus" name. The bottom line of the issue is who are you seeking to please your earthly Father or your heavenly father? Honoring your Father and Mother does not mean you should dishonor the Heavenly Father in the process.
Would your father close his prayer in the hebrew name not to offend you? So why should you close in the false name?
There is nothing in the scriptures that talks about "secret faith" The early believers lived their faith and proudly proclaimed the name of the Father and the Son even in the face of persecution and certain death. We are not called to be undercover agents in Mashiach. That being said, there is a fine balance between boldly proclaiming what you believe and being obnoxious. The Ruach must guide you and tell you when to continue bearing witness and when to wipe the dust off your feet.
Yes YAHUWAH knows our heart, but He is looking to see if the words on our lips (the fruit of our lips) matches with what is in the heart.
Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O YAHUWAH, my strength, and my redeemer. Psalm 19:14
Please receive these words prayerfully,
