For nearly a hundred years our study and instruction focused on commands. In the current concept, Christians obey commands because it is required. Obedience does not occur to accomplish God's purposes. It occurs to respect authority. In this common concept, obedience is divorced from God's purposes and objectives.
Obedience focuses on respecting authority.
Some Christians think obedience is not concerned with God's purposes. Understanding the requirements is unimportant. Obeying the requirements in a manner that accomplishes God's purposes is unimportant. Faith is reduced to compliance with a check list. Jesus' concept of obedience focused on serving.
