I love this and have been trying to think of myself as irreplaceable in God's eyes. More importantly, if we can find out why people around us are so irreplaceable to God by building deep relationships or trying to take on the perception that God sees the world, I will be able to love people a whole lot better.
"Egotism is pathological self-obsession, a reaction to anxiety about whether or not I really count. It is for our acute self-conciseness and can be prevented and healed only by the experience of being adequately loved. it is, indeed, a desperate response to frustration of the need we all have to count for something and be held to be irreplaceablee"
