Some general notes:
1:22 – Love one another as if your lives depended on it.
2:9 – You are the ones chosen by God, chosen for the high calling of priestly work.
2:11-17 – Be a living example so that your actions refute the way of the world. Do not make yourself comfortable in this world. By doing good, you will cure the ignorance of those who think you’re a danger to society.
4:7-11 – Love each other as if your life depended on it. Love makes up for almost anything. Be quick to feed the hungry or shelter the homeless. Be generous with what God gave you so that all may share.
5:6-7 – Be content with who you are and don’t put on airs. God’s strong is on you; he’ll promote you at the right time.
