What is the significance of 'yea' and 'nay' in the Christian faith?

In the sermon, the preacher highlights that 'yea' (yes) represents affirmation and agreement with God's truth, while 'nay' (no) stands as a clear rejection of that which contradicts it. This binary communication is essential for Christians as it upholds the faith principles that guide our lives. By affirming the truth in our words, we demonstrate trust in God's character and promises. The avoidance of equivocation promotes a faith that is straightforward and rooted in reliance on God, freeing believers from the burden of false promises and miscommunication.
