If it is true that it isn't easy to swim against the current, it is also true that it is always right to make the effort to keep ourselves above the waves. This makes us progress.
In order to do the work of spiritual healing—healing ourselves or healing others—we must learn to turn to God in prayer, to listen to divine Mind, which governs us. We must also challenge ways of thinking that are very much accepted and even supported in the world—beliefs which assume that God's power cannot heal, while asserting aggressively that matter can heal and that mankind should look to it for aid.
Confronting and overcoming such beliefs can be difficult at times. But we have taken this path of Christian healing because of something, and this something is God, infinite Truth.
