Everyone who listens to these words of mine and acts on them will be like a wise man who built his house on rock. (NAB) Matthew 7:24
We live in a world that makes listening to the word of God very difficult. There is much to distract us in the materialness of life. Then there is the distraction of the flesh, where pornography pulls you into a way of life you would not have ventured until it was shown to you. We are being fed the seeds of evil by promoting what is not of God's ways nor of his virtues.
The words that were spoken by Jesus is our guide in life, when we listen and take to heart his words it will be the true path you will always walk. When your faith is so strong that no matter what happens to you in life, your faith is your guide, because you took to heart what Jesus preached on the mount. That is what he means about our houses built on solid rock. Not physical houses but faith. If your faith is weak and you encounter struggles and temptations , and you stray from faith then your house is not built solidly. Take to heart his words and act on them, let them be your path in life, then your house will be built on a solid foundation.
