God promises blessings but requires obedience to receive them. The story of Naaman illustrates this - he was healed of leprosy only after following Elisha's instructions to wash in the Jordan River, despite his initial objections. In general, the document argues that while God's grace is free, obedience to his commands is necessary to enjoy blessings, as shown in passages like Matthew 7:21 and Hebrews 5:9.
