The conditional preservation of the saints, or commonly conditional security, is the Arminian Christian belief that believers are kept safe by God in their saving relationship with him upon the condition of a persevering faith in Christ. Arminians find the Scriptures describing both the initial act of faith in Christ, "whereby the relationship is effected", and the persevering faith in him "whereby the relationship is sustained." The relationship of "the believer to Christ is never a static relationship existing as the irrevocable consequence of a past decision, act, or experience." Rather, it is a living union "proceeding upon a living faith in a living Savior." This living union is captured in the simple command by Christ, "Remain in me, and I in you" (John 15:4).
