something i learned this saturday at a special worship service on saturday(which was great btw):

main lesson was john 21:15-19

interesting pointer: 1st time jesus asks peter whether he loves him, he uses the term "agape" to ask whether he loves him; peter responds with the love "phileo" an affectionate, but not unconditional love, ditto w/the 2nd time.
3rd time, jesus finally uses the term "phileo" to ask whether peter loved him; THAT'S why peter was hurt; some ppl think it's because he was asked 3 times, which somehow reminded him of his triple denial. that's quite possible, but this is also another meaning. it's as if jesus finally asks, "so this is where you admit you're at?" what's great is that, despite peter responding affirmatively, jesus still bestows the charge he gave peter after the 1st or 2nd time; take care of my sheep.

interesting pointer: sheep were taken care of in the past so that they could be USED; specifically for meat and clothing. that's what we have to become to others; when we take the term of proverbial christian sheep, we choose to sacrifice ourselves in order to serve others.
