I find it interesting that children without fathers, in the past at least, were called bastards.
Perhaps it is no surprise that fatherlessness has such a negative impact on children such as dropping out of school, behavioral problems, drug and alcohol abuse, runaways, and so on.
We are legitimatized when we accept Jesus, as we are adopted into God’s family.
Romans 8:14 For those who are led by the Spirit of God are the children of God. 15 The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, “Abba, Father.” 16 The Spirit himself testifies with our spirit that we are God’s children. 17 Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
Non-Christians are effectively spiritual bastards, which is why they spend their lives chasing after every other thing to attempt to satisfy that identity and purpose that they don’t have.
Part of the disconnect happens, even in saved Christians, because they don’t fully understand that they are legitimatized in Christ. So they hang onto worldly desires and pleasures.
