The Law......

Blessed is the man whom thou chastenest,

O LORD, and teachest him out of thy law;

Psalm 94:12

"The law of God was changeless in its character, and therefore

Christ gave Himself a sacrifice in behalf of fallen man, and Adam lost Eden and was placed with all his posterity upon probation.
Had the law of God been changed in one precept since the expulsion of Satan from heaven, he would have gained on earth after his fall that which he could not gain in heaven before his fall. He would have received all that he asked for. We know that he did not.... The law ... remains unalterable as the throne of God, and the salvation of every soul is determined by obedience or disobedience...."
