I believe God can use anything to teach us. What He uses first and foremost is His word. He teaches un in the book of Timothy that His Word is profitable for instruction. As I have been studying on laziness, it struck me how the person who observes the lazy man mentions the lessons and instructions that he received from observing the actions of the lazy man. This can be found in Proverbs 24:30-34. The lesson that the observer learned is that laziness can lead to poverty and that poverty can come on suddenly.
The Bible teaches us to watch and pray that we fall not into temptation. Watching means that you are observing all that goes on around you and that you recognize when God is trying to teach you things through the lives and activities of others. God’s desire for you is to grow in faith and in the knowledge of your Lord and Savior Jesus Christ. Your growth is dependent on God giving you instruction as to what you should be looking at. Be quiet enough to hear God when He gives instruction no matter where the instruction comes from. He may be warning you of impending destruction.
Grow in God with Sow the Word, where we are sowing the Word into the heart of man.
