Why Keep the Commandments?

I helped my son prepare and deliver this short talk in Primary:

Heavenly Father created all of us.
Jesus Christ atoned for our sins.
If we love them, then we will keep their commandments.
To know their commandments, we must read the scriptures.
If we keep their commandments, they will send us blessings.
The greatest blessing of all is to become like God.
In the name of Jesus Christ, Amen.
