Believing and trusting in God with your heart without the need to see him is faith. It is by faith that we are saved and it is by reading God's Word that we receive our faith. In God's Word he teaches us to exercise our faith for the promise appropriate to our needs. It is assurance of this faith we believe that it is going to happen.
Hebrews 011:001 Now faith is the substance of things hoped for, the evidence of things not seen. 011:006 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. 012:002 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. Romans 001:017 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith. 004:020 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; 004:021 And being fully persuaded that, what he had promised, he was able also to perform. 005:001 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ: 005:002 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God. 010:017 So then faith cometh by hearing, and hearing by the word of God. 012:003 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. Galatians 002:016 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. 003:026 For ye are all the children of God by faith in Christ Jesus. 003:022 But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe. 003:023 But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed. 003:024 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 003:025 But after that faith is come, we are no longer under a schoolmaster. 003:026 For ye are all the children of God by faith in Christ Jesus. Philippians 001:027 Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel; 003:009 And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: 1 Corinthians 013:013 And now abideth faith, hope, charity, these three; but the greatest of these is charity. 016:013 Watch ye, stand fast in the faith, quit you like men, be strong. 2 Corinthians 005:007 (For we walk by faith, not by sight:) Ephesians 002:008 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 006:016 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. Matthew 009:020 And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment: 009:021 For she said within herself, If I may but touch his garment, I shall be whole. 009:022 But Jesus turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour. 017:020 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you. 021:022 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive. Mark 009:023 Jesus said unto him, If thou canst believe, all things are possible to him that believeth. 011:022 And Jesus answering saith unto them, Have faith in God. 011:022 And Jesus answering saith unto them, Have faith in God. 011:023 For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. 011:024 Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them. John 003:016 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 005:024 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life. 014:012 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. 014:013 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 014:014 If ye shall ask any thing in my name, I will do it. James 001:002 My brethren, count it all joy when ye fall into divers temptations; 001:003 Knowing this, that the trying of your faith worketh patience. 001:004 But let patience have her perfect work, that ye may be perfect and entire, wanting nothing. 001:006 But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. 001:007 For let not that man think that he shall receive any thing of the Lord. 005:014 Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: 005:015 And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. Luke 017:006 And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.
Romans 10:017 So then faith cometh by hearing, and hearing by the word of God.
