The Kingdom of Heaven suffers violence and the violent take it by force. Matt11:12.
As it was in the days of John the Baptist and Jesus so also now the gospel is being preached and is being attacked. The gospel is the fire of God and it turns the sinner into a saint. How powerful is that? The kingdom of darkness will resist this and it will attack every claim that it makes. Today we see this in every area of life. The gospel is the power of God unto salvation to all those who believe. God’s power will topple every principality and power. It is the power of God that will save you. No other power can save you. When you see His power you will desire it and leave all to claim it as your own. Satan and his minions will resist you all the way. This is why you need to fight for the kingdom of God in His power. You cannot do it on your own strength. You have to align yourself with His power. This is achieved through fasting and prayer. In the Spirit, you will be able to take the Kingdom of Heaven by force. All the benefits of the Kingdom are yours but you must claim it by force. The force here is not a physical force but a determined and earnest desire to obtain all that you are destined to have. The enemy will try to rob you of these things but you have to fight him in the Name of Jesus. This is spiritual warfare.
