1 John 3:18-20

Young's Literal Translation

¹⁸ My little children, may we not love in word nor in tongue, but in word and in truth!

¹⁹ and in this we know that of the truth we are, and before Him we shall assure our hearts,

²⁰ because if our heart may condemn -- because greater is God than our heart, and He doth know all things.
