Do you believe there is victory in Christ?
Watch Dr. David R. Reagan's lovely video above and you will know so.
I also researched on a few Bible verses* that give heart and point to Christ's Victory over that which is not of God.
1 John 5:4 NIV
4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith.
1 Corinthians 15:57 NIV
57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
Romans 8:37 NIV
37 No, in all these things we are more than conquerors through him who loved us.
2 Corinthians 2:14 NIV
14 But thanks be to God, who always leads us as captives in Christ's triumphal procession and uses us to spread the aroma of the knowledge of him everywhere.
Philippians 4:13 NIV
13 I can do all this through him who gives me strength.
Deuteronomy 20:4 NIV
4 For the your God is the one who goes with you to fight for you against your enemies to give you victory.
Hebrews 4:12 NIV
12 For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
