Yes, but as it specifically relates to the living God, only one act of Faith or faithing that if done continually will result in recieving the Spirit of Christ.
Vines: " a personal surrender to Him and a life inspired by such surrender."
The a,b,C's of Faith! An act, based upon a Belief, sustained by confidence.
I have a Strong's expanded exhaustive concordance of the Bible and Pisteuo #4100 says -
to have faith (in, upon, or with respect to, a person or thing), to entrust (especially one's spiritual well being to Christ). It goes on to say, Pisteuo means not just to believe, but also to
be persuaded of; and hence, to place confidence in, to trust, and signifies, in this sense of the word, reliance upon. You and others who promote salvation by faith + works seem to be very fond of the Vines definition - "a personal surrender to Him and a life inspired by such surrender" and there is a reason for that. Now allow me to break it down for you.
John 1:12 is attached with "a personal surrender to Him" in Vine's definition. John 1:12 - But as many as
received Him, to them He gave the
right to become children of God, to those who
believe in His name. There is the personal surrender to Him. When we choose to believe in/have faith in Christ unto salvation (Acts 16:31; Ephesians 2:8) we are entrusting our spiritual well being to Christ, along with placing confidence, trust and reliance in Him for salvation. That would be a personal surrender to Him, resulting in justification (Acts 13:39; Romans 5:1) and that is the ROOT of salvation.
The FRUIT would be living by or "out of" faith, as we see 2 Corinthians 5:7 attached with "a conduct inspired by such surrender" in Vine's definition, which reads -
For we walk/live by faith and not by sight. This is our continued walk with the Lord by which by or "out of" faith, believers bear fruit/produce works. So faith in Christ is the ROOT of salvation and "a conduct inspired by surrender" which FOLLOWS and produces good works would be the FRUIT. You are using the Vines definition to mix cause and effect/fruit of faith with the essence of faith and the end result is salvation by faith + works.
So to believe in Christ unto salvation is to have faith in/trust in/reliance in/confidence in Jesus Christ alone for salvation. Obedience which "follows" is WORKS. The Greek words for "pistis" and "pisteuo" are two forms of the same word. "Pistis" is the noun form, "pisteuo" is the verb form. *Nothing in the root meaning of either word carries any concept of works.
If you believe in Christ for salvation, then you are trusting in Him alone to save you. This belief/faith results in actions appropriate to the belief (to one degree or the other/all genuine believers are fruitful, yet not all are equally fruitful - Matthew 13:23) - but the fruit/actions/works are NOT INHERENT in the belief.
*Prior to my conversion, while still attending the Roman Catholic church several years ago, I was also confused about this and basically "defined" faith "as" obedience/works just as all works-salvationists do.
If you believe in/have faith in Christ unto salvation, then you are trusting in Him alone to save you. This belief/faith results in actions appropriate to the belief/faith (to one degree or the other/all genuine believers are fruitful, yet not all are equally fruitful - Matthew 13:23) -
but the fruit/actions/works are NOT INHERENT in the belief/faith.
