It's never safe to do your best in a trap during the journey. It's hard to pray for God's blessing, just like sailing on the beach to explain marriage.

This sentence describes a situation in marriage, that is, both parties encounter difficulties on the way, similar to sailing on a high beach, which is difficult to cross. At this time, both sides need to work together and do their best, but even so, it is difficult to guarantee their safe survival.

In this case, love in marriage may be put to the test. If the two sides can't cope with the difficulties together, they may be deadlocked or the relationship may break down. So this sentence is also reminding people that in marriage, we need to support each other, advance and retreat together, and tide over the difficulties together.
