Matthew 7:24a (23–27) “Therefore everyone who hears these words of Mine and acts on them,”
I think that by this time Jesus has made Himself pretty clear, that God has established a way for us to be saved from the judgment to come and a way for us to live while we wait for that day. Any other way Jesus calls “lawlessness”.
Anything that is working outside the plan of God as described in scripture is lawless or out or order, it goes against what God has planned. So, we have one of two options, we can either follow the plan (7:24) or not follow the plan (7:26). Because we live in a corrupt world bad things always happen, 7:25, 27. But if you stay with the plan you will be fine in the end (that final day of judgment).
The house we build has been described for us in His sermon (Matthew 5–7). We are all faced with that choice to act on Jesus words and follow Him or not. Paul puts our first step simply this way, “that if we confess with our mouth Jesus as Lord, and believe in our heart that God raised Him from the dead, YOU WILL BE SAVED” (Romans 10:8–10).
Faith involves acting on the knowledge that our trust on His name will keep us on the Day of Judgment.
