Romans 10;17

Hebrews 1:1-3  Now faith is the substance of things hoped for, the evidence of things not seen. ²For by it the elders obtained a good testimony.  ³By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.

James 1:5,6   If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him. ⁶But let him ask in faith, with no doubting, for he who doubts is like a wave of the sea driven and tossed by the wind.

Romans 4:5   But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness,

Ro  5:1,2  Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, ²through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God.

Faith heals and makes whole-

Romans 1;17  For in it the righteousness of God is revealed from faith to faith; as it is written, “The just shall live by faith.”

Ro 3:22-26  even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference; ²³for all have sinned and fall short of the glory of God, ²⁴being justified freely by His grace through the redemption that is in Christ Jesus, ²⁵whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, ²⁶to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus.

As a defensive weapon -
