Certainly, I would enjoy sharing what I have experienced.
I have found that if I don't love my wife's children then I don't love my wife. So I have learned (with Jesus leading me) and put extra effort how to teach my step-daughter in ways that I wouldn't with my biological children - I mean she has different needs than what my own children have. My parenting methods that I have employed in the past with my own children don't fit her character very well. Therefore, I took the initiative to adapt to that instead of the other way around. I wouldn't want to burden a teenage kid to adapt to my style with all of their newly found pressures in life, and I am happy and willing to serve the Lord in this way - I think it is one way Jesus is teaching me about things I was dead to before.
This is working wonderfully and has allowed my relationship to grow with her, my wife AND my biological children. Win, win, win! Family is not defined by blood, but by those that walk with Jesus in the Holy Spirit. Jesus has brought me to this point where I am looking at ALL people differently, I am hopeful that this newly found view is converging to Jesus' perspective of people.
Praise the Lord Jesus Christ! Amen!
