It means much to be willing to make our sacrifices to win our way homeward or heavenward. Purity, perfection, virtue, and goodness are realized only through the law of sacrifice.
In the pure affections of soul is the true image and likeness reflected; therefore Christian Science, through loyalty to God and an active demonstration, demands a sacrifice of every false affection. If we wish to be Christians, we must learn to be loyal to Truth, to our brother man, to our Leader and Teacher, and to ourselves. If we are faithful over a few things, God will make us ruler over many.
True sacrifice means that we must give love for hate; good for evil; peace for discord, until we reach a point where our loyalty and sacrifice bear fruit; then we can give peace for peace, love for love, and joy for joy.
