"walk the walk"! Nor are his ears open and attentive to God's Word. As Jesus says in Matthew 13:15:

For the heart of this people has grown dull. Their ears are hard of hearing, and their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their heart and turn, so that I should heal them.
And do this, knowing the time, that now it is high time to awake out of sleep; for now our salvation is nearer than when we first believed. The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light. (Romans 13:11-12)
