Obeying the law will save you if you obey it perfectly. You have not done so up until now. You will not do so in the future.

There is only one person Who has obeyed the law perfectly. That is Jesus Christ. Since He has obeyed the law perfectly, He has the right to request and receive anything from His father... anything. He has requested you... if you believe on Him. He will not debase Himself below you. But He will take you with Him if you accept Him.
