All of us like compliments, but why? I think a large part of the reason is that they serve to either validate our own healthy sense of self-perception or, if we have an unhealthy self-perception, they serve to bring hope that we just might be better than we perceive ourselves to be. Compliments serve as confirmation that we are, indeed, valuable. Receiving compliments is necessary to a healthy development of one’s self-perception. A failure to receive compliments can cause someone to doubt their own value, and may lead to them doing abnormal things to solicit compliments so they can be reassured of their own value.
Of course, there is always the temptation to pride when one receives compliments. That’s where a health Christian theology comes in handy. We recognize that everything we are, and everything we do, is because of God’s grace. He is to be thanked for everything we are/do, and thus we redound the praise to the glory of God.
