Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me.
Revelation 3:20 (NKJV)
Picture this—we open two doors for Jesus Christ to enter into our lives.
In Genesis, Jesus is the sin offering placed at the door of every unbelieving heart, and those who open the door and believe in Him will begin a new life through Him. In Revelation, Jesus is the Saviour who stands and knocks on the door of every believing heart, and those who answer and welcome Him will experience the presence and power of His life in them.
The first entry is for salvation, and the second is for fellowship.
Fellowship with Christ is crucial for our spiritual growth and well-being.
The context of Revelation 3:20 is Christ's revelation to the Church of Laodicea (Revelation 3:15-20). When Jesus asked the Laodiceans to "open the door" for Him to enter, He was asking them to repent, that is, to change the direction of their Christian lives. The believers in Laodicea were materially prosperous but spiritually impoverished. They reasoned that because life was good, so would their relationship with Christ. However, Jesus redefined a good life as anyone who has an ongoing and intimate relationship with Him.
Lots of believers only "open the door" to God when they are in crisis or pain, but the truth is that Jesus wants to fellowship with us all the time—not just when we are "wretched, pitiful, poor, blind, and naked" (like the Laodiceans).
True intimacy with Christ changes your priorities and your future because it aligns your life with what He has in store for you. When you pay attention to and draw near to the One who blesses us with abundant life, you will find safety and security because He has the power to produce "renewable energy" in you to overcome any demand or difficulty. Then, as you grow in the revelation of God's perfect love, you will have unwavering faith in His goodness.
