The Apostle Paul said we were to both “test ourselves” with regard to the intellectual content of our faith and also to “prove ourselves” with regard to the veracity of our spiritual life: “Put yourselves to the test (ἑαυτοὺς πειράζετε) to see if you are in the faith; prove yourselves (ἑαυτοὺς δοκιμάζετε) to see whether Yeshua the Messiah lives within you – lest you fail the test and be disapproved (ἀδόκιμος)” (1 Cor. 13:5). Notice that the verb “to prove” (i.e., dokimadzo: δοκιμάζω) means to test something by fire (like a precious metal) to discover its quality and purity. The analogy here is straightforward. The quality of our faith will be revealed during times of testing and hard circumstance. Do we walk in love, joy, and peace – despite the testing of this life? If our faith regularly fails in the crucible of testing, we may need to reexamine its authenticity (Prov. 24:10).
A proven faith is one that evidences the Fruit of the Holy Spirit, though other characteristics include an abhorrence for personal sin and the desire to obtain God’s forgiveness; a hunger and thirst for God’s righteousness to be manifest; a sincere willingness to obey the LORD and keep His commandments, and a heartfelt love for God and others. These characteristics mark genuine teshuvah (“repentance”), that is, a turning away from inner darkness to the light of the Divine Presence. Teshuvah is a miracle that transforms the person so that the inner life is restructured and made into a new creation by means of God’s grace (2 Cor. 5:17). Spiritual rebirth implies a new heart with a new set of affections: “I am crucified with Messiah; it is no longer I who live, but Messiah who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me” (Gal. 2:20).
