You have a good point here @chuksdozie2004, but please I must say something here. I think what determines whether love conquers or not is not the gravity of what is to be conquered, but the kind of love involved. When God sent his son to die for us, the gravity of what was to be conquered was THE SINS OF THE WHOLE WORLD, but yet God's love conquered it. If God's love conquered the sins of the whole world, then tell me what that love can't conquer.
God's love is more powerful than anything it comes against. Whether it be hatred, or sickness, or even death, God's love is above.
From Romans 8 vs 35-39, we can see that nothing can separate us from the love of God, not even death, angels, demons, this life or the life to come. That's the power of God's love!!!
