Romans 8:31

“What, then, shall we say in response to this? If God is for us, who can be against us?”

This is a great verse to comfort us when we feel like the whole world is against us. That may be so, but with God we will always be on the winning side.
Like it or not, while we are in these mortal bodies, we are in a spiritual battle. We are in enemy territory. Satan has dominion over the world (the dominion God had given to Adam, which passed to him at the Fall). His desire is that all mankind would be enslaved to him and worship him as God. So when we stand up for the true and living God, you can be sure that Satan is not happy about that. Nor is the world system, for as well as being ultimately under submission to Satan, it is also propagated through sinful man and his selfish desires. These desires are for the things that are evil, because to indulge in them is to (often unconsciously) rebel against God. Those who stand for righteousness are a thorn in the side to the people of the world. Despite people saying their life motto is to ‘do right by other people’ (because they have a false notion that if their good deeds outweigh their bad deeds, they will go to heaven), when other people are doing more right than them, they want to bring them down.
It’s been said before on this blog, but it never hurts to say it again: we need to see these things from God’s eternal perspective. Recall how Elisha’s servant despaired because of the Syrian army, but Elisha told him not to be afraid, because ‘those who are with us are more than those who are with them.’ (2 Kin. 6:15-17). As well as God being on our side, we have the angelic host of heaven. We read in Psalm 34:7, “The angel of the LORD encamps around those who fear him, and He delivers them.” When we are on God’s side, we have nothing to fear.
