Note from Tim: Over the next two days I will be publishing a short devotional each morning (I began HERE). I originally wrote these devotions for the Winter 2018-2019 issue of Open Windows and I have permission to republish them. I pray they are an encouragement to you in your walk with Christ!
Devotional Passage: Ephesians 2:18-22
“So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone…” – Ephesians 2:19-20
If the foundation of your house is not solid, the entire house will shift. Imagine what damage this shifting would do to a building made out of stones. When a large structure, such as a temple, was built with stones in New Testament times, there was an essential stone that ensured a solid foundation: the cornerstone.
It was not a ceremonial stone with things inside of it like a time capsule. That is what a cornerstone is today. Then, it was usually the largest stone, and it was carefully cut and painstakingly laid so that it could be the basis for lining up all of the other stones.
Our faith is not built upon important people or philosophies; our faith is built upon the doctrines of the gospel passed down to us by the Holy Spirit through the apostles and prophets. Yet the unrivaled cornerstone that everything else is measured upon is not an idea or simply an important person, but the Lord of glory in the flesh. Our only cornerstone is Jesus Christ!
Father, I praise You for not only giving Your precious doctrines
but also for giving Your beloved Son.
He Must Become Greater 
I thank God for this verse. I serve on a short term mission group that builds the shelter for the very poor in Guatemala. As we build the foundation with cinder block and concrete I scratch this verse into the cornerstone. As we speak to the family over the course of the two days we speak of this truth, that without Christ as the firm foundation we crumble.
That is powerful, Marianne! Praise God for your work & thank you for sharing!
