In my time with the Lord yesterday it hit me that all three of these verses reveal a common pattern of spiritual growth:

• "So Jesus was saying to those Jews who had believed Him, 'If you continue in My word, then you are truly disciples of Mine; and you will know the truth, and the truth will make you free" (John 8:31-32).
• "So, faith comes from hearing, and hearing by the word of Christ" (Rom 10:17).
• "Blessed is he who reads and those who hear the words of the prophecy, and heed the things which are written in it; for the time is near" (Rev 1:3).

We can't expect to grow in intimacy with the Lord if we don't actively spend the time to cultivate that growth.  As these verses show, we grow in our faith by reading the Bible, which moves into us being able to hear the Lord's voice, then solidifies as an active faith (i.e. we go from simply 'believing' He's real to being able to keep/heed the prophecy as faithful witnesses).
