We tend to go to extremes. In regard to the gospel of Christ, it's important that we not emphasize one aspect of salvation at the expense of another. And if we've not been giving enough emphasis to faith, we need to be reminded how crucial faith is in God's plan of salvation. But in supplying this deficiency, we need to be careful.
True faith means more than mental agreement with the facts of the gospel.
It is certainly a fact that we must believe the truth. If we don't, we'll be lost. But the faith we must have in order to be saved involves much more than mere mental assent to Jesus' deity. It means trusting Him enough to obey Him. Faith is the very best foundation for obedience that we could ever have.
