My mother asked me once if I was taking my one aspirin a day. I replied that I didn't do anything religiously...not even religion. I reckon she's a bit worried about me, but what can I do?
That said, there is one 'habit' that I have found useful and meaningful, though I don't even do this always and consistently. When I am looking into scripture, I see just two characters...Him and me. When He's speaking to the Pharisees, He's speaking to me, not to some long-dead Jewish guys. In the law, in the History, in the parables I just want to know where and who HE is and where and who I am.
John 5:39 You examine the scriptures carefully because you suppose that in them you have eternal (age-abiding) life. Yet they testify about me.
Two characters. "You and Me"
2 Timothy 3:16. All Scripture is God-breathed and is useful for teaching, for reproof, for correction, and for training in righteousness.
Two characters. "God-breathed" and useful teach, reprove, correct, and train me in righteousness.
I don't have the moral or spiritual luxury to 'search the scriptures' looking for interesting Theological tidbits. If I don't find HIM, then I've found nothing for my reproof, for my correction, and for my training in righteousness. Believe me, with ME, that's a full-time job.
Not to say that Doctrine isn't important. On the contrary, it's vital! If you had asked me 8 months ago if I thought that what a person believed doctrinally had any effect on what kind of person they were, I would have denied the connection. Mostly, I think, because I'd seen so few examples of a truly Godly, Christ-like life among people with strong religious convictions. Indeed, we've all seen deep evil in people of every religious persuasion who hold their beliefs strongly. But something Ray said in one of his lessons rang like a bell in my spirit. He said that people email him saying that if people believed like him, they would be inclined to go out and live it up. And Ray answered that, no, if people believed exactly like him, they would behave like him. It IS the doctrine which plays the largest role in training us in righteousness. Many ARE called, and few ARE chosen.
Anyways, that's what came to mind to share on reading your question.
