well two things come to mind.
When talking about the gospel one cannot escape talking about God's laws. For instance, we have the law of sacrifice, the law of obedience and the law of consecration. There are other laws as well, but one in particullar has caught my mind lately. The law of the gospel.
Can anyone explain to me what that is? Remeber, it is not the lawS of the gospel but the LAW of the gospel (singular).
1 is when Christ is asked what is the greatest commandment, and when he is asked what is needed to enter into the kingdom of heaven.
Which was, Love God, Love men, Give up everything and Follow Christ.
