Hereby know we # 62_1JO_04_06 # We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. 
Hereby know we # 62_1JO_04_13 # Hereby know we that we dwell in him, and he in us, because he hath given us of his Spirit. 
hereby know we # 62_1JO_02_05 # But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
