Let us say them to ourselves or think them often. If we will keep thinking and saying the Truth we see, we shall soon know more Truth. God is Truth. When we speak truth we speak of Good. When we speak contrary to Good we do not speak truth.
Truth is everywhere.
We may think and speak it wherever we wish. God is Good and God is everywhere. Let us think and speak this frequently. Say it even when things do not look good. This is true faith.
