1. God and Christ fight for us. (2 Chr 20:17)
    Ex 14:13, Jn 16:33, 1 Jn 3:8, Rom 8:36-37, Eph 2:16

2 Chronicles 20:17 Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of the Lord with you, O Judah and Jerusalem: fear not, nor be dismayed; to morrow go out against them: for the Lord will be with you.

Exodus 14:13 And Moses said unto the people, Fear ye not, stand still, and see the salvation of the Lord, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever.

John 16:33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.

Jesus, the Christ, destroyed our enemy, the devil. (1 John 3:8, Ephesians 2:16)

1 John 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

Ephesians 2:16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:

God grants us who believe in Jesus the Christ to be overcome in all things. (Romans 8:36-37)

Romans 8:36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.
37 Nay, in all these things we are more than conquerors through him that loved us.
