I really enjoyed reading these passages as a number of songs came to mind when reading these verses. I remember singing the song about The Man who Built his House on the Rock and the significance of that to me as a child. How important it is to have a firm foundation in our faith, so that when hard times come we are able to rely on God and trust Him to carry you through them.
Another song popped into my head when reading Mathew 7:7-8. Seek Ye First is in the name of the song which comes from these verses. These verses are a great reminder to continually learn about God and ask Him to show you His ways. It doesn't say to only do it once, but to continually pursue God.
Reading Mathew 7:1-5 talks about judging others. How easy it is to pick out faults of others and criticize without looking at ourselves first. Verse 2 is a good reminder to me to remember that I will be judged the same way I judge others, and is a sobering thought. This is a good reminder to look at myself first before saying anything about others around me.
These are just a few tidbits that I took from these passages.
