There is a faith inherent in man that is nothing more than wishful thinking. From his own life influences, his mind believes. His confidence possesses no assurance except that which he imagines himself.
True faith, though, is something you know that you know that you know, and the Holy Spirit within confirms that its source is God. The faith described in the Bible does not apply to what Christians can imagine and then hope and pray that God will come alongside it; it originates from God and will reveal itself as naturally as we breathe. We may struggle with the details and delay of time before its manifestation but this is when we are called to walk by faith, or more accurately, to trust in the faith He has already given us. As sure as God has called us, He will call faith to work itself through us as he deals also with our covetousness and idolatry; the carnality that invents and believes selfishly in itself, but questions and challenges true faith.
"...for it is God who works in you, both to will and to work for his good pleasure." (Philippians 2:13)
