Revelation 1:18
"I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death."
They often say that the man with the keys is the person who is in charge. Whenever I am at a church, I always know that the pastor will have the keys to every door because he is the person in charge. When the person in charge resigns or loses their position, they are always told they need to turn in their keys.
The verse above says that God has the keys. In other words, this verse is teaching us that God is ultimately in charge. When you got saved, you not only received salvation, but you also received access to the One Who is in charge of all things. I find there are several things to which God holds the keys.
First, God holds the keys to death. I don't know if you quite understand what this means, but God is ultimately the One Who determines when death will come your way. Psalm 116:15 says, "Precious in the sight of the LORD is the death of his saints." Christian, just like God made you to fill a position in this world, He also prepares your death to give Him glory. We often talk about God preparing our ways in life, but we often forget to remind people that God also prepares our death. You have nothing to fear about death, for God conquered death and will only allow it to come your way when He has prepared you. That is why you often see those whom God has prepared not afraid when they are at death's doorstep. God prepared them for that time. When the shadow of death comes your way, you have nothing to fear for God holds the keys of death.
Second, God holds the key of knowledge. In Luke 11:52, Jesus rebuked the lawyers because they rejected the key of knowledge. Jesus is the key of knowledge. One of the biggest travesties we see today is how our education system has kicked Jesus out of the public school system. They wonder why grades are dropping, and the answer is they kicked the key of knowledge out. You will never gain the knowledge you need in any area without including God in your life. Yes, you may acquire some knowledge, but God holds the keys to unlock all knowledge.
Third, God holds the key to the house of David. This sounds strange, but it is important that you understand what these keys hold. This represents that Jesus is the royal possessor. In other words, Jesus will take the throne of David someday and will rule the world. Because He has the key to the house of David, it means that He is the stronghold against the enemy. It means that He is the One who can unlock the closed doors in your life. It means that He has the keys to the treasure house. In other words, God has the resources to supply all your needs. No matter what you face in your daily life, God has the keys to supply those needs.
One thing you can rejoice about today is that God is the One Who has the keys. He is in charge of everything in life, and when He chooses, He can unlock the doors to your needs. Whatever your need is today, you can talk to the One Who holds the keys to unlocking the resources to supply your need. Prayer is the key to unlocking the resources for your needs. Don't let there be a day when you forsake your opportunity to talk to the One Who holds the keys for your day.
