You were once an orphan too

Despite whether your father and mother played a significant role in your life, you came into this world a sinful human. Not only did you do sinful things, but you were sin simply because you were born of a sinful race. This sinfulness left you as an orphan: no inheritance in the kingdom, abandoned to rely on your own ability to advance and grow, without a Heavenly Father.

From the very first day of your life you needed a Heavenly Father to reach down out of heaven, to scrub you clean and to adopt you into His heavenly family. At some point, you realized that you were a sinful child, living in a sinful world, in need of a heavenly Father and you asked God to forgive you. You stood at the gates of Heaven and asked to be welcomed in.

God, your new Heavenly Father, adopted you into His family where you now experience love, have an eternal inheritance, and are forgiven forever through the death of His Son, Jesus Christ.

Gal 4v1-7 (NLT)
1 Think of it this way. If a father dies and leaves an inheritance for his young children, those children are not much better off than slaves until they grow up, even though they actually own everything their father had.2 They have to obey their guardians until they reach whatever age their father set.3 And that's the way it was with us before Christ came. We were like children; we were slaves to the basic spiritual principles of this world.
4 But when the right time came, God sent his Son, born of a virgin, subject to the law.5 God sent him to buy freedom for us who were slaves to the law, so that he could adopt us as his very own children.6 And because we are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, "Abba, Father."7 Now you are no longer a slave but God's own child. And since you are his child, God has made you his heir.

Rom 9v15-17 (NLT)
15 So you have not received a spirit that makes you fearful slaves. Instead, you received God's Spirit when he adopted you as his own children. Now we call him, "Abba, Father."16 For his Spirit joins with our spirit to affirm that we are God's children.17 And since we are his children, we are his heirs. In fact, together with Christ we are heirs of God's glory. But if we are to share his glory, we must also share his suffering.
