My sister's snorkelling analogy that i couldn't remember:

wearing goggles is like opening up our spiritual eyes to Jesus

the snorkel helps us to breathe in fresh air, the Holy Spirit

flippers are a reminder that we need god's word in order not to give the devil a foothold

when we point others to the fish and corals, we're showing others God's beauty and what he can do through us, we're inviting those who don't see it yet to come off the boat and join us.

the life vest is our CG.
