Sensual unbelief results from us paying more attention to the physical world and/or our natural senses, or paying more attention to the opinions of others, instead of focusing on the Divine, Supernatural Truth of God. Consequently, we keep looking to Christ Jesus to do for us what He ALREADY has done in us!
The biblical definition of faith, and by extension the definition of belief, is NOT: knowing and affirming truth, with the exception of being obedient to God’s Divine Truth. However, the definition of intellectual assent IS: knowing and affirming truth, with the exception of being obedient to God’s Divine Truth. Intellectual assent also is defined as: a decision made in our minds that lacks the full commitment of our hearts (human spirits).
No matter when we respond favorably to either the written or the preached Word of God, the Divine Truth is that our positive response is because of God’s Grace and His Holy Spirit’s Power. That’s right! It is because of God’s Grace the Power of His Holy Spirit that God allows His Holy Spirit to influence our receptivity of the read, preached, and/or taught WORD of God, which is the Gospel of Christ Jesus. Furthermore, it is because of this initial act of God’s Grace and Power that His Grace and His Holy Spirit’s Power next work together to breathe life into us, again, only this time it is the “new” life that is being breathed into our spiritually dead human spirits. God, in essence, is regenerating sinners’ spirits—we are being born again from Heaven.
