1. What is faith and why is it so critical to the believer’s survival?

And the Lord said, Simon, Simon, behold, SATAN HATH DESIRED/ASKED FOR/BEGGED (aiteō/G154) TO HAVE THEE, that he may sift  ( siniazō/G 4617)  you as wheat

But I have prayed for thee, that thy faith/pistis/G4102 fail not: and when thou art converted, strengthen thy brethren  (Luke 22: 31 – 32).
2. The meaning of faith/pistis/G4102 in the scriptures
Since faith/pistis/G4102 is used exactly in the texts, we need to explore its meaning from the root word peithō (G 3982).  Since Peithō is used in the following ways in the New Testament, we see that it means:
a. Trust  or confidence
  • Trusted G3982 in GodMark 27: 43.
  • Trust G3982 in riches – Mark 10: 24
  • … he taketh from him all his armour wherein he trusted G3982   – Luke 11: 22
  • he spake this parable unto certain which trusted G3982 in themselves  – Luke 18: 9
  • I have confidence G3982 in you through the Lord – Galatians 5: 10
  • Being confident G3982 of this very thing – Phillipians 1: 6
  •  But I trust G3982 in the Lord that I also myself shall come shortly – Phillipians 2: 24


b. To be persuaded to believe  or to be persuaded about a belief or to hold a strong belief

  • But the chief priests and elders persuaded G3982 the multitude – Matthew 27: 20
  • And if this come to the governor’s ears, we will persuade G3982 him, and secure you – Matthew 28: 14
  • If they hear not Moses and the prophets, neither will they be persuaded, G3982 though one rose from the dead  – Luke 16: 31
  • all the people will stone us: for they be persuaded G3982 that John was a prophet. – Luke 20: 6
  • persuaded G3982 them to continue in the grace of God – Acts 13: 43
  • certain Jews from Antioch and Iconium, who persuaded G3982 the people – Acts 14: 19
  • knowing therefore the terror of the Lord, we persuade G3982 – 2 Corinthians 5: 11
  • And some of them believedG3982 and consorted with Paul and Silas… – Acts 17: 4
c. To obey
  • as many as obeyed G3982 him, were scattered, and brought to nought…  – Acts 5: 36
  • O foolish Galatians, who hath bewitched you, that ye should G3982 not obey G3982 the truth, – Galatians 3: 1


d. To agree with someone

  • And to him they agreedG3982 – Acts 5: 40



3. Conclusion

We see that faith means  trust/confidence in God,  persuasion about the truth of God, obedience to God,  agreement with and belief in God. Satan’s intent was to tempt Peter in order to cause him to lose this spiritual inheritance.

Let us therefore fight the good fight of faith and lay hold on eternal life in spite of the fiery trials that beset us. Blessings, peace and angelic prosperity to you.
