God said that those who obey God's word can go to eternal rest, heaven.
Everyone has weaknesses that only they know.
God is well aware of our shortcomings, so he helps us to fix our shortcomings so that we can be blessed.

This is because heaven is a place where we cannot go with our shortcomings.

God wants God's children to realize the value of heaven.

God wants you to live like a child of God, even if there is sadness and pain on this earth.
When we obey the word of God and have a grateful heart, we can go to eternal heaven.

Hebrews 4:11–12
Let us, therefore, make every effort to enter that rest,
so that no one will perish by following their example of disobedience.
For the word of God is alive and active. Sharper than any double-edged sword,
it penetrates even to dividing soul and spirit, joints and marrow;it judges the thoughts and attitudes of the heart.
