You listen to Jesus' wisdom and His Word, and you'll have a solid foundation for your life that will not be swept away when troubles come. God will keep you safe if your founding is in Him. Yet, when I read this, I see the foundation as something basic. Just like a solid foundation is the most basic and most important part of an actual house, there's still far more to be built. And what can be built can vary in size and quality.
As I've written about before, one of the primary mandates of the church to spread God's Kingdom to all the earth:
And one of the ways we extend His Kingdom by letting our light shine:
In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven - Matthew 5:16
And how can we let our light shine? By building a house of beauty and quality that glorifies God. People will see an inviting house and want to come in.
So how does one build a beautiful house? One way is by growing in the Spirit through learning and instruction in the Word. What's learned is not just knowledge, but it's the understanding and discernment that comes from knowing the details and the framework of the situations presented in the Bible.
Consider it similar to the difference of someone like myself who has no idea how to build a house attempting to build one vs an experienced contractor building one. At best I could build a ramshackle hut out of wood with questionable structural integrity. Sure, I'd put my best effort into measuring and cutting precisely to build something to be best of my own ability, but ultimately the result of me "doing it on my own" without any instruction, learning, or training would be a rather uninviting house that I'd doubt many would want to live in.
Yet, if someone were learned in building houses were to make one, you could expect it to not only be built soundly, there'd be more than just wooden walls. There would be plaster walls, windows, electricity, carpeting, plumbing, and air conditioning just to name a few additional qualities.
The point being the difference between the two would be quite stark. One, despite being well built (or as well built as I could do it), would be made of the only the most basic material and could barely be considered a house, let alone something one would consider living in. The other would be something people would see and want to come in to take a look.
I've experienced this in my own life a couple different ways.
The first is one of the things that I'll eternally thank my parents for doing: they enrolled me in a Christian school from kindergarten up to 6th grade. There were many benefits to this, one of them being I received education in the Bible for all of those years. Unlike many children who may only get exposure to the Bible during Sunday school, I was exposed to it every school day as well. I didn't really understand the value of that until I was much older. No, I didn't become the perfect little boy that built a beautiful house at such a young age to astound all those around me in my piety. I definitely strayed far and wasn't what I'd call any type of shining example of a Christian life. But, what it did do was instill a blueprint of right and wrong that stayed with me throughout my life even when I thought I was smarter than the Bible. I didn't always listen to this sense of right and wrong, but it was always there to convict me when I did something I knew was wrong. And that blueprint has been key in the building of my own Spiritual house.
The second, and more recent, comes from a New Testament survey class I took at our church earlier this year. What this class did was provide the context for all the books of New Testament. Not only who wrote the books, but whom they written to, why they were written, and what was going on at the time they written. This was beyond valuable to me because while I've always had a decent grasp on certain Bible verses in the New Testament, the difference is about the same as my house building example. Knowing a specific verse is having just one facet of the passage. Having the details and the context fleshes it out.
For example, while the meaning to John 14:6 is not hard to understand, one gets so much more meaning out of it when one knows that Jesus was answering one of the disciple's doubts about not knowing the way to where Jesus was going and that the gospel of John focused on Jesus' divinity. On top of that, this was happening during Passover where Jesus was drawing closer to his own crucifixion, so Jesus was saying a lot of confusing and very heavy stuff. And this is just one simple example.
This type of learning has led to a growth in the Spirit that has allowed me to relate situations in my life easier and recognize patterns of behavior. It has allowed me to become more mature Spiritually which has allowed me to build a more beautiful house on His solid rock foundation. There's complexity and detail in all of God's designs and it's easy to gloss over them, and be happy with, the bare basic meaning. Yet, it's in the details and the framework of these designs where God reveals His wisdom.
So, if you want to grow Spiritually, learn the Word. Do not just read it, but really learn about it. One of the primary sources that was used in our class was New Testament Survey by Merrill C. Tenney, which is very good at explaining the books of the New Testament. I highly recommend anyone wanting to know the beginnings of our church and what the New Testament is all about to read it in conjunction with the Bible itself.
And lastly, by building a beautiful house for God through learning His word, you will not only be an attractive light for others to extend His Kingdom, but you will also allow God to do more in you.
