I think the article is great overall. The analogy about the envelope was okay but I think something better is appropriate. For example, as a father, my kids have requirements to do around the house and other duties they cannot neglect. Even though they sometimes mess up, they still get gifts from me all the time just because I love them. I think likewise, all who are sons of God and obey God's sovereign will, will receive gifts from God including salvation. I'm not sure if that's a good analogy but I would like to see more analogies of how gifts work but duties are involved by the receiver. Thanks.
