Knowing how something is built is not the same as knowing how to build it.
Part owner of a construction company years ago, it was my job to know how walls, ceilings, and floors were constructed and to know when these were built according architectural specifications; but to actually do the building was totally different. Building skills are only learned by building.
Likewise, the Bible tells us how to be godly but learning how to do it comes from experience. As a young preacher I knew a lot about how following Christ was done but I am still learning how to do it.
Jesus said,
“Here’s what I propose: … If someone strikes you, stand there and take it. If someone drags you into court and sues for the shirt off your back, gift wrap your best coat and make a present of it. And if someone takes unfair advantage of you, use the occasion to practice the servant life. No more tit-for-tat stuff. Live generously… love your enemies. Let them bring out the best in you, not the worst. When someone gives you a hard time, respond with the energies of prayer…If all you do is love the lovable, do you expect a bonus? … You’re kingdom subjects. Now live like it.” (Matthew 5:38-48 Message)
There are things we must learn how to do if we expect to be of service to Christ.
How are you going to learn how to “turn the other cheek” unless someone slaps you? How am I going to learn how to love my enemies unless I have enemies? How are you going to learn how to pray for those who spitefully use you unless you have a boss that throws you under the bus or co-workers that spread malicious gossip? How am I going to learn how to trust God to provide unless I sometimes lose my job or go through difficulty?
We say, “God why would you let me get slapped in the face?!”, when all God is doing is teaching how live for Christ instead of just knowing how living for Christ is done.
