Just as Mephibosheth wasn’t born crippled, Adam was created in a state of innocence. Since his sin, all human beings have been born sinful, like Mephibosheth condemned because of his ancestry. David makes an enquiry for Jonathan’s sake, pointing to God taking the initiative and forgiving us for Jesus’ sake. David will give Mephibosheth all Saul’s land and he shall eat at his table as a member of his family. Christians are adopted into the family of God.
