There was a time that I thought I should be able to adhere to the Jewish law of the Old Testament. Jesus said that He didn’t come to abolish the law, but to fulfill it, and He never broke that law. The part I missed was that He had fulfilled it! We are no longer subject to the law, but really we never were; it was set in place for the Jews. Jesus died on the cross to set us free from the religious bondage set by men! Never should we be subjected to religious ordinances set in place to keep us in-line!
Why do you close your eyes when you pray? Isn’t it something you were taught? In John 17:1, it says that Jesus looked up to Heaven and prayed! He didn’t bow His head and close His eyes! Now if your preacher says bow your head and close your eyes, you probably should, they have their reasons, but if you are doing it because you think it’s biblical, you’re wrong. This is just showing how we are misled by man. You can keep bowing your head and closing your eyes if you want, there’s nothing wrong with it. It’s just an example to get you thinking.
These have indeed an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but they are of no value in stopping the indulgence of the flesh. Colossians 2:23
