Love covers over a multitude of sins

1 Peter 4:8 "Above all, love each other deeply, because love covers over a multitude of sins."

I googled the above verse to understand it better and I realise the context of the verse is about showing love and understanding and seeking peace and harmony in a social setting where people use their gifts to serve one another.

1 Peter 4:8-10

Young's Literal Translation (YLT)

⁸ and, before all things, to one another having the earnest love, because the love shall cover a multitude of sins;

⁹ hospitable to one another, without murmuring;

¹⁰ each, according as he received a gift, to one another ministering it, as good stewards of the manifold grace of God;

In group fellowships, there may be instances where we notice one another's shortcomings, so usually people prefer to overlook them and focus on offering goodwill and hospitality. It is like loving our neighbour as ourselves - just as we would not like to dwell on our own shortcomings because we love ourselves, we would usually also show the same love to others in normal daily circumstances when they fall short of the mark (as long as they are not intentionally hurting others) since we are all imperfect human beings. 

Proverbs 10:12

Young's Literal Translation (YLT)

¹² Hatred awaketh contentions, And over all transgressions love covereth.
