Numbers 12:7 My servant Moses is not so, who is faithful in all mine house.
Picking up where we left of yesterday, this first use of faith in the KJV is related to actions by Moses in response to God asking Moses to do what was asked of him. It was a conversation, God spoke to Moses yet God is spirit, so how is it that Moses could hear God?
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
First faith is given to each of us, but having that faith does not guarantee that we can hear God. That only comes if we put our faith, our belief, our trust in Jesus Christ. Then faith comes by hearing and hearing by the Word of God.
Isaiah 35:4-6 Say to them that are of a fearful heart, Be strong, fear not: behold, your God will come with vengeance, even God with a recompence; he will come and save you. Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped. Then shall the lame man leap as an hart, and the tongue of the dumb sing: for in the wilderness shall waters break out, and streams in the desert.
These prophetic words from Isaiah were speaking of the coming Christ by whom we are saved by faith. It is then and only then that we can hear by faith.
Romans 10:8-9 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
The word of faith came before your salvation but was only activated in us after confession and belief.
