23Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed. 24So then, the law was our guardian until Christ came, in order that we might be justified by faith. 25But now that faith has come, we are no longer under a guardian, 26for in Christ Jesus you are all sons of God, through faith.  Galatians 3:23-26
Knowing the rules of God could never turn you into a child of God. Committing yourself to doing all the good things commended and commanded by the Law could not turn you into a child of God. Avoiding breaking one of the commands of God’s Law could not make you a child of God.

No. Only faith jn Jesus makes you a child of God. Now the Law makes us aware of how much we desperately need a Saviour! Yes, the Law makes us wise for salvation. But its your faith in Jesus Christ that gives you the status of being a child of God. As His child you have full access to Him. Trying to be good, trying not to break the Law will never be enough. So God has gotten rid of that category of “good enough” for us. He sent Jesus to fulfill the Law completely!

Putting our faith in Jesus is an incredibly dynamic and powerful act! You will always be God’s child through faith in Jesus.
