Faith Is The Victory!
I believe that faith in Jesus gives a person the victory to overcome the world. Whether that overcomes sin which separatesus from God or it overcomes sinful thinking that hinders our relationship with God.
Victorious faith in Jesus comes from the Word of God. Which is why I cannot overemphasize the importance of feeding up it daily. Because a lack of knowledge concerning God's Word was Israel's downfall (Hosea 4:6). When people do not have access to His word, they are very weak. (Amos 8:11-14)
Even Jesus utilized the Word of God to overcome Satan's temptation (Matthew 4:4,7,10).
Why would you deprive yourself of the means that God has given you to produce saving Faith? (James 1:21)
