How do we know faith is attacked by Satan?

Satan specifically aims to undermine the grace of faith, especially when an individual is at their most humble and vulnerable state. When a repentant soul approaches Christ, they often face suggestive doubts such as whether Christ is able to save them or extend mercy. This psychological assault is a clear indication that faith is under attack. These challenges can come in the form of questioning God's character and His willingness to save, which serves to divert one's attention away from the truth of the Gospel and the assurance given by Christ's atonement.
