This idea is cousin to praying first, last and always. Life isn’t always easy, so make use of the equipment available to you when you can!
There are two things that make reading the Bible each day so important. The first is that the Word of God is the only living, breathing Bread of life. It matters to every person every day for all of time. Pray (first, last and always) while you read it and let it comfort you because of past hurts, meet you where you are in the moment and prepare you for what is to come.
The second is that this world can be a rough place. There are a lot of things out there that can distract and deceive you. Some of it is downright evil, aggressively and out-rightly bringing destruction. Other things may be evil, but more subtle in its attack; seductive temptation can destroy the complacent. Other things aren’t evil at all. They could even be good things distorted by obsession or distraction from what you are supposed to be doing. With all these things that could draw us from God, arming yourself appropriately is just sensible.
The Bible is so very relevant, and is something you can assuredly stand upon. Don’t take my word for it, or any other person’s. Don’t only read books about the Bible, or sermons teaching on the Bible. When Jesus died on the cross the curtain dividing the Holy of Holies from the people ripped. We have direct access to God! You can read the Bible and understand it; you can pray directly to the God of all creation!
Christ died to allow for this. He did it on purpose for that very reason—to reconcile us to God. We no longer need priests and other go-betweens. We are adopted children, loved and accepted.
When you live out your day, you will meet with ideas and practices to which you will need to respond—in approval, in rejection or with apathy. To respond rightly, you must know the Truth. How will you unless you fill yourself with Truth as a regular diet?
Just like I said in the prayer post, reading your Bible each day is not a chore or something to feel guilty about when you miss. Feel privileged. Feel responsible. Know what it cost for you to be able to read that book. Know that it would be utter folly to walk out in the cold without the proper winter gear—and equally foolish to walk in this world without Truth coursing through your thoughts.
