Men were created to provide for the physical needs of God’s family. For those men that have laid with a woman and have children with her, his commitment is required as a part of his salvation. A first wife and children are not things that can be abandoned and replaced with another woman and her children. A man is accountable for his entire family.
Jesus said, “For unto whomsoever much is given, of him shall much be required: and to whom men have committed much, of him they will ask the more.”(Luke 12:48)
If a man has been given a wife and children, much is required. He cannot walk away from his family. And for those men that have committed themselves to their first wife and children more will be asked of them because his family members trust and love him.
