Ephesians 2:8, 9 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, that no one should boast
After Jesus claimed to be sent by God, some were seeking to seize Him, having come to the conclusion that He was not a good man. But others did believe in Him, "and they were saying, 'When the Christ shall come, He will not perform more signs than those which this man has, will He?'" (John 7:31). All the evidence was there. Some chose to believe; others chose not to. People do the same today. Faith is a choice. We choose to believe or not believe.
Faith is the operating principle of life. It is the means by which we relate to God and live our lives in freedom. Notice the variety of ways stated in Scripture by which faith affects our lives.
First, we are saved by faith (Ephesians 2:8, 9).
Second, we "walk by faith, not by sight" (2 Corinthians 5:7).
Third, being found faithful is a prerequisite for ministry: "I thank Christ Jesus our Lord, who has strengthened me, because He considered me faithful, putting me into service" (1 Timothy 1:12).
Paul then adds, "And the things which you have heard from me in the presence of many witnesses, these entrust to faithful men, who will be able to teach others also" (2 Timothy 2:2). This is more than being reliable, since a person could be counted on to follow through on an assignment and not be a believer. The added ingredient in faithful people is that they know the truth and can be counted on to be reliable.
Fourth, the quality of any relationship is determined by faith or trust: "Many a man proclaims his own loyalty, but who can find a trustworthy man?" (Proverbs 20:6). The words faith , trust and believe are all the same word ( pistis ) in the original language. The man who has faith believes in something. The one who believes also trusts, or he doesn't truly believe. There is no concept that looms larger in life than faith because what we believe determines how we live.
