When a young man has his Bar Mitzvah, he is becoming a man. This is a great time to wish him luck in future endeavors, as well as build his self esteem with some positive messages about him. Make it a funny message if you think it would be appropriate.
It’s exciting to see you grow up to become such a dynamic young man. We hope you have an awesome Bar Mitzvah.
Keep working hard and we are sure you will do great things with your life. Congratulations on becoming a young man.
Congratulations to you on this momentous and joyous occasion. It’s a great right of passage and a milestone in your life. You will look back on this time with sentimental thoughts.
Congratulations on growing up and becoming a man. This is a great milestone in your life, and I am glad I was able to celebrate with you.

We are excited that we get to celebrate your coming of age celebration.
I should probably warn you now that you have become a man and had your Bar Mitzvah. Life doesn’t get any easier from here.
Enjoy your time of independence as a young man while you can. It probably won’t be long before you have some sweet young lady to tell you what to do. We are wishing you the best.
A little secret is that adulthood is not as great as it is worked up to be. This is exactly why we have a celebration. It’s to trick you into thinking it’s a good thing to come of age. Congratulations on becoming an adult.
Just think. If you weren’t Jewish, you’d have another fifteen years or so to still screw around and act like a child.
Well, you're officially all grown up.
What does it feel like to be all grown up. I'm wondering because I still haven't grown up.
Adulthood is still fun. It's just that you start thinking of fun in a different way.
Being Jewish has some benefits. For example, there are the Bar Mitzvah gifts!
You are destined for and deserving of great things. This milestone in life will be something that you can look back on as a valuable and important step on your journey toward success.
