tn The conjunction καί (kai) which begins 3:22 is epexegetical (explanatory), relating a further implication of the “confidence” (παρρησίαν, parrēsian) which believers have before God when their heart (conscience) does not condemn them. They can ask things of God with the expectation of receiving their requests.

tn The ὅτι (hoti) is clearly causal, giving the reason why believers receive what they ask.
