Abraham 3:26; “And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever.”

Romans 4:4-7; “Now to him that worketh is the reward not reckoned of grace, but of debt.  5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.  6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, 7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.”

Trying to work your way to heaven will only lead you to being judged under the Law.
