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 invite Jesus Christ into our lives by opening two doors.
In Genesis, Jesus is described as the one and only perfect sin offering, crouching at the door of every unbelieving heart, and whoever opens the door and believes in Him will begin a new life through Him. In Revelation, Jesus is our faithful Saviour, standing and knocking at the door of every believing heart, and whoever answers and welcomes Him will encounter His presence and power in new and unexpected ways.
The first entry is for salvation, while the second is for fellowship.
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 urging them to repent, that is, to change the way they lived their Christian life. Holding on to possessions will never satisfy you. It is possible to have everything and still feel empty.
The believers in Laodicea were materially prosperous but spiritually poor. They assumed that because life was good, their relationship with Christ was equally good. However, Jesus redefined what it means to have a good life as someone who is in constant fellowship and connection with Him.
Most believers only "open the door" to God when they are in crisis, pain or suffering, but the truth is that Jesus longs to fellowship with us all the time—not just when we are "wretched, miserable, impoverished, blind, and naked" (like the Laodiceans).
When you give attention and draw near to Christ who gives you life, you will find stability and safety because He has the power to produce "renewable energy" in you to face any demand or difficulty. True fellowship and intimacy with Christ change your priorities and your future because it aligns your life with what He has planned for you.
