Being a Christian is more than just an instantaneous conversion – it is a daily process whereby you grow to be more and more like Christ.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing.
Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
