Parents' love is not undefinerable because it's a great bond that holds families together because before we can accept that we like someone that shows that there's love between each other.
According to bro Eli's sermon he said that respecting or considering the ordinary from things of men. You know, he said that he wonders why parents are mothers or fathers? I will not like it. Their even they are disrespectful, no parents wouldn't love his/her children because there's a bond that conjoined them together as a family, according to book of (matt 7:9) says or what man is there of you, whom if his son ask bread, will he give him a stone.
Matt 7:11 says if he then, being evil, knows how to give good gifts unto you children, how much more shall your father which is in heaven give good things to them that ask him? This shows how great our love is, he being our provider because this chapter says if we can give our own a good gift how much more our father who is in heaven it shows God loves us because our God is kind unto unthankful and to the evil and good people.
In this present world we have seen some parents that don't like their children. The reason is that maybe they're not on good terms like before or because of problems with their children but as parents fall in these kinds of categories let's regain the love back, according to (1 Peter 3:4).
