Yes, both are necessary for a Christian and for our world too. Why do I say this? Because there are so many people who don’t want to admit this or hear it. Prayer and praise go together with faith and all of it is needed today. Because life and living today is hard enough without having faith in a future with Jesus. Prayer and faith go hand in hand, but it seems that many people don’t believe in having faith in a God which they can’t see. You can’t touch or see any of the “gods” which are worshiped in the world today, many of them are actually dead and in their graves yet people still think that they are “gods”. If they were then they wouldn’t be dead!
Satan is a fallen archangel, a guardian seraphim and one that once lived on the “mount of God” but pride brought him down because he thought that he could be like God and take God’s place. No one can do that but he convinced enough of the angels to follow him until there were a third of the angels thrown down from Heaven. We don’t know how many this was, but considering how much our world is in such a mess today it was a LOT!
Today it seems that nobody wants to acknowledge God as the Creator, but He is and He is NOT dead! Seek Him out while there is still time to do so. Read John 3:16,17; Romans 8 too, because they tell you what and Who you should know and why.
