Habakkuk 2:4 See, he is puffed up; his desires are not upright – but the righteous will live by his faith. (NIV)
Behold, his soul which is lifted up is not upright in him: but the just shall live by his faith. (KJV)
Matthew 17:20 – 21 (also covered in Mark 11:22, Luke 7:6) 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 and it shall remove; and nothing shall be impossible unto you. Howbeit, this kind goeth not out but by prayer and fasting. (KJV)
Note: (NIV has no verse 21 which is the statement about fasting.)
Matthew 21:21-22 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done. And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
Mark 4:30-32 Again he said, what shall we say the Kingdom of God is like, or what parable shall we use to describe it, it is like a mustard seed, which is the smallest seed you plant in the ground, yet when planted, it grows and becomes the largest of all garden plants, with such big branches, that the birds of the air, can perch in its shade.
Read the story of Mose’s (Exodus 14:13-31) parting the Red Sea using God’s power, through his faithfulness. God told Moses to part the Red Sea, and to lead the people through it. Through an act of Living Faith and trust in the Lord, Moses demonstrated God’s glory to his people. This is also an active example of the above verses regarding moving mountains.
Sometimes, living by faith can be difficult, but at those times you just need to remember that to live by your faith and trust God, or to not live by your faith and not trust God is always a decision that you make….it is not a feeling that you have! If you have trouble believing then you can always pray to God for him to help you with your unbelief. (Mark 9:24)
