Faith

“For everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith.” (1 John 5:4 NIV)

Faith – Bible Dictionary definition:

“Belief, trust, and loyalty to a person or thing. Christians find their security and hope in God as revealed in Jesus Christ, and say "amen" to that unique relationship to God in the Holy Spirit through love and obedience as expressed in lives of discipleship and service.” – Baker’s Evangelical Dictionary

Faith - Bible’s definition:  

The most definitive definition of faith in the Bible is, “Now faith is confidence in what we hope for and assurance about what we do not see.” (Heb. 11:1 NIV) 

It’s impossible to please God without faith

“And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.” (Heb. 11:6 NIV) 

The above verse explains that faith comes by doing  two “musts”

1)    You must believe that He is.

2)    You must believe that He rewards those who earnestly seek Him.

Faith is asking and believing without doubt

“But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind.” (James 1:6 NIV)

Examples of faith in action

An old woman has a child: “And by faith even Sarah, who was past childbearing age, was enabled to bear children because she considered him faithful who had made the promise.” (Heb. 11:11 NIV) 

A blind man is healed: “Go,” said Jesus, “your faith has healed you.” Immediately he received his sight and followed Jesus along the road.” (Mark 10:52 NIV)

Therefore…

“Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, for you are receiving the end result of your faith, the salvation of your souls.” (1 Peter 1:8-9 NIV)

“For we live by faith, not by sight.” (2 Cor. 5:7 NIV)
