“I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture.” John 10:9 ESV

Valuables are kept protected, usually under lock and key. Every major bank in the world has a secure vault to store tangible assets away from would be criminals. Access into that valuable space is only through having the key or security code to enter. Your own personal valuables are kept secured by whatever means you choose to protect them. Entrance into your assets again is only possible by the one who holds the key. Can you imagine having the most valuable possession known to man not under lock and key, but having free access to it, no key needed?
Jesus says, “I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture.” (Jn.10:9 esv) Most doors have locks on them. The more value behind the door the bigger and stronger the lock, at least that is how it works in our fallen world. Jesus says He is the door to salvation, eternal life after our live on earth is over. He also provides for us in this world finding pasture. Is there anything of more value than that. I think not! Yet, there is no mention of a key needed to open the door of salvation. No security codes or secret passwords are needed to enter through the door.
Salvation, as valuable as it is, is a free gift. Jesus paid it all on the cross of calvary. Our sin debt is paid. All we sinners need to do is to repent and accept Christ as our savior for payment of our sins. Jesus unlocked the door by His death and resurrection for all who believe in Him. No key needed.
