we are from the truth

People living according to the truth is spoken of as they were "from the truth." Alternate translation: "we are living according the way Jesus taught us" or "we belong to him who is true" (See: rc://en/ta/man/translate/figs-metaphor)

we assure our hearts

The word "heart" here refers to feelings. Alternate translation: "we do not feel guilty" (See: rc://en/ta/man/translate/figs-metonymy)
