It's a joy to be with family. Often, as Salvos, we're called to be a father or mother to kids who simply need us to fill these roles for them. We must be ready to do so at any point. This only happens when we are available to others in our daily journey and it can happen without any specific work on our part.
There is a pain in the hearts of couples who are unable to have children. The alternatives are not as workable for every couple, but there are ways in which a person can connect in a paternal way. Not a replacement for a child of your own, but a role to fulfill for the glory of God.
I'd be lost without my family. Everyone needs one.
Joel 3:17 (AMP)
17 So shall you know, understand, and realize that I am the Lord your God, dwelling in Zion, My holy mountain. Then shall Jerusalem be holy, and strangers and foreigners [not born into the family of God] shall no more pass through it.
