1 Peter 3:8

8 Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind.

This verse is pretty simple, but important. We should live with unity of mind, with fait, not doubting God. 1 James 1:6-7 tells us,

"6 But let him ask in faith, with no doubting, for the one who doubts is like a wave of the sea that is driven and tossed by the wind. 7 For that person must not suppose that he will receive anything from the Lord; 8 he is a double-minded man, unstable in all his ways.”

We should be sympathetic to those around us, have brotherly love, and a tender heart, all of which help us in following the second greatest commandment, to love our neighbor as ourselves (Mark 12:31, Matthew 22:39). Finally we should have a humble mind. We have Jesus as an example for this; during his time on earth he displayed great humility, despite the fact that He was the person most deserving of arrogance, as He was, and still is, God.
