Matthew 1:24 Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
When you consider the role and importance of stepfathers, remember Joseph. His stepson was the Son of GOD, the Creator knew Joseph would be a worthy steward and father to HIS Son.
Being a stepfather is as important as being the childs actual father.
So if you feel like you’re spinning your wheels trying to raise a stepchild, remember, whatever you do directs that child in their adult life.
