God is the king of His kingdom.
His law is the perfect law, thus so high up.
Because of sins, we can't have the ability to achieve the perfection to be in His kingdom.
God is not only the righteous God, but the merciful God.
Jesus, His son died for us not to lower the standard of law, but as the saviour of us from sins.
When we yearn to go into the kingdom, our old self died, and as God has promised when Jesus went back to heaven, we are given a new life, with Holy Spirit living in us.
With His power, we achieved the perfection.
And once we are in His kingdom, we are forever His citizen, and the perfect law is no longer impossible to follow.
