Think wisely. There is much to know in a thousand plus worthy subjects. Make your primary pursuit Scripture. After that, you will have to choose wisely where your efforts go in what you study. Yes, all truth is God’s, but that does not mean it is equally valuable.
Think deeply. For subjects worth studying, push yourself. Most of us can go deeper than we realize.
Think in community. We all need others. We need their perspective and to hear how they process important truths.
But never forget that all this thinking well is pointless if it does not motivate us to love God and others more.
