Now you, brothers, like Isaac, are children of promise. At that time the son born in the ordinary way persecuted the son born by the power of the Spirit. It is the same now. But what does the Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.” Therefore, brothers, we are not children of the slave woman, but of the free woman.<Gal 4:28–31>

God called the children of God to be saved "children of promise like Isaac." "Isaac" means "smile."
Isaac was truly the source of laughter for his mother, Sarah. We, too, should bring a smile to Heavenly Mother's face. Heavenly Mother is most pleased when she finds her lost brother and sister and holds them in her arms.

 Moreover, we the people of Zion who have returned into Mother’s arms earlier should always be joyful according to God’s word, so our brothers and sisters who come later can smile and laugh a lot.

Let us smile at each other, and share joy and gratitude with one another as much as possible. Zion must be a place where everyone, regardless of gender, age or position, always feels happy, overflowing with joy and blessings.
