would you like to talk about Jesus?
Man's anger could never never bring about the righteous life required of God . In our anger and anxieties we look to Him not letting the sun go down on man's anger . He gives us His faith by which we can hear His voice called the "hearing of faith" (his) acknowledging he has spoken from heaven . It is not of us after the imaginations of ones own heart. It is not of ourselves.
Faith works two ways. Faith of God generated from heaven of Christ and the faith that says we hear him generated by our new spirit towards him called in Christ (not from Christ)..Our amen
So in regard to...."Faith in WHAT and WHO and WHY". It is in regard to the faith of God as the WHAT and WHO. And WHY so we can hear him and have fellowship with His Holy Spirit, the Spirit of Christ who indwells the believer according to the working of His faith in us..making His faith that He works in us to both will and do his good pleasure perfect as a imputed righteousness.
