In 1 Corinthians 16:8-9, Paul said God opened a door to him. God still opens door for His children. God opens door to missionary opportunities. Also, there is a door of prayer. This door is open to everyone. You do not need the permission of anyone before you pray. You are free to pray anytime and anywhere. Even when a government outlaws prayer like it happened in the time of Daniel, those like Daniel will still pray. Any government that passes such an obnoxious decree must be prepared to stay awake 24/7 because some of us may choose to start our prayers at 3am. How effective have you been using your open door in prayer? Your success in the Christian faith depends on how you utilize this door. You cannot be anything of repute in God’s Kingdom if you neglect this door. One thing that is common to those who rise and fall from the faith so often is that they fail to utilize their open door in prayer. A prayer-less Christian is not only powerless but also a misrepresentation of Christian faith, will end up a victim and will struggle in His walk with God. Power is released in the place of prayer. You need power to live as a Christian (John 1:14). Without such power, Heaven will be a mirage. If you are neglecting effective prayer life, it means you do not want to go to Heaven.
You are neglecting this open door when you see the need to pray but procrastinate, saying “I will pray about it tomorrow”. That tomorrow may never come. Or when you have a negative dream but only mutter some positive confessions and push it aside or leave it to fate by saying “If God delights in me, He will do something about that dream so I leave it to Him”. You also neglect this door when you see a sharp or major character flaw in your spouse, or leader but rather than intercede, you make it a subject of discussion or gossip. Do you know that about 70% of what happens to most believers could have been averted if only they have effectively utilized their open door in prayer? There is gross prayerlessness in Christendom today. Repent and never take anything for granted. Monitor your dreams and revelations and make the most of them by the door of prayer.
For the prayerful, prayer is a sieve which determines what they will go through and what they will not, while the prayer-less goes through everything projected their way by the enemy.
