Agreed, love, agape, is the most central theme of the New testament and bible as a whole. Without it Christianity is nothing and with it, Christianity is everything. Love encompasses the teachings of the prophets, Jesus and Paul and the disciples.
Good job on your essay:) Its so very true. Love is an easy thing to talk about but sometimes very hard to show and do. Thank God we have the Love of Christ in us to show others and Christ to give us strength to do it and how to do it, even when its so very hard.Praying for you.
