The LORD is my light and my salvation; whom shall I fear? The LORD is the stronghold of my life; of whom shall I be afraid?
I know for a certainty that I have a kind and loving God. Therefore, from whom should I flee? of whom shall I be afraid [Psalm 27:1]? For I know that He is a God who is kind and loving toward humanity. If you can be convinced of this on the basis of this word ["kind," Titus 3:4], [then] there is no doubt. Then follows praise and thanksgiving, and you do not remain joyless but say: "Now this is a God who does not send lightning and thunder down on me, but who wills to deal with me in a kind and loving way." He is always with you; whether you are awake or asleep, you have faith in your heart; wherever you go, He is present; He speaks with you and you with Him, and there is mutual conversation between Him and you. He speaks with you like a good friend [Exodus 33:11], and you in turn praise, proclaim, and call upon Him.
