'But as many as received Him, to them He gave the right to become children of God, to those who believe in His name' John 1:12
We don't deserve anything from God. But God gives, He's gracious. John 1:12 says that God offers us rights in His courtroom. In other words: God is able to give us a claim on His goodness. Once you have 'God-rights' you can make a claim. You get 'God-rights' by receiving Christ; believing and relying on Jesus.
When we have a right to God's goodness God is bound to respond out of His own joy. God offers us the right to become His children. He asks us to receive Christ and call Him Dad. He wants us to enjoy His Fathering.
