This is how I explained it to a group of Bar Mitzwah boys:
If your dad gave you a shiny new sports car, you wouldn't hesitate, you'd jump in and go for a spin, let it loose, see what that car could really do.Your new Godly soul will take you anywhere you want to go (in any world!!) much faster than the fastest planes or rockets ever invented. Jump in and see.
טעמו וראו כי טוב השם - taste and see that HaShem is good.
