"What shall we then say to these things? If God be for us, who can be against us?" (Romans 8: 31)
In Christ, we are more than conquerors (Romans 8: 37).
He did all the fighting, and He overcame all things:
"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." (John 16: 33)
Jesus has overcome the world, and that includes all things in it.
Yet before we can understand that Jesus has overcome all things, we have to see that He overcame the greatest hindrance to our lives: sin and death:
"13And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; 14Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; 15And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Who can be against you today?" (Colossians 2: 13-15)
Jesus overcame sin, death, and the Devil through His Work on the Cross.
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world." (John 1: 29)
Jesus fulfilled the law, so that Satan can no longer use the law against us:
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill." (Matthew 5: 17)
Jesus also judged the Devil:
"And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: 9Of sin, because they believe not on me; 10Of righteousness, because I go to my Father, and ye see me no more; 11Of judgment, because the prince of this world is judged." (John 16: 8-11)
The prince of this world has been judged, found guilty, and will be put away forever:
"And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. 11And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death." (Revelation 12: 10-11)
The Devil is defeated!
The world is overcome, too:
"4Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world." (1 John 4: 4)
"4For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. 5Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?" (1 John 5: 4-5)
God is for you today, Beloved, because of Jesus, for in Him you are accepted (Ephesians 1: 6)
Whatever may be against you, know that God is for you today!
