1. Everyone with emunah that Yehoshua (Yeshua) is the Rebbe, Melech HaMoshiach has been born of Hashem, and everyone having ahavah for the One having begotten has also ahavah for the one begotten by Him.
2. By this we have da'as that we have ahavah for the yeladim of Hashem, when we have ahavas Hashem and we are shomer over His mitzvot.
