Not allowed to have faith? Maybe the point is that our faith comes by Christ's faith(fulness) - true faith is not of our doing but is a
fruit of the Spirit.
[Gal 5:22 KJV] 22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
[Rom 3:22 KJV] 22 Even the righteousness of God [which is] by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
[Gal 2:16 KJV] 16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
