The Lord never ceases to invite us to come unto him. He wants to gather us around him always just as any parent wants their children near. Unfortunately God is governed by spiritual laws that create stipulations for entering into his presence. Were it not so he would probably not be so adamant about us being righteous and obeying a set of commandments. He tells us, though, that if we enter into his presence unworthily, it will be like hell. Yet another reason why his commandments are an example of his mercy, not his desire to reign supreme and dictate to his minions.
