What do those verses mean to you?
Do you know what I think? I think God put those verse there especially for unmarried people. I think it's His solution to the crusade of crushes, flirting, daydreaming, castle-building, and discontentment that runs rampant in even our Christian circles. And even in our own lives, sometimes.
I mean - think about it: it's all there.
Vs. 23 - Guard your heart. Use diligence. Why? Because that's where your life source is. That's where who you are stems from. And you want it to be pure and good and focused solely on Christ.
Vs. 24 - Don't speak boldly and flirtatiously. In fact, don't say anything that could be counted as unfitting to a disciple of Christ. Put such things far away from you. Let it be completely out of character for you to be boisterous and loud and giggly and attention-grabbing.
Vs. 25 - Let your eyes be focused on one thing, and one thing only: Jesus. Let Him be your life and your goal, and your source of happiness. Keep your vision fixed on where He is, and where He wants you to be. Remember eternity. Look at life through His eyes, through His perspective. Don't get distracted.
Vs. 26 - Think about where you're going. Think about who you are. Don't wander into situations that you will regret later. Don't let life just happen to you; you have a purpose and a calling. Follow it. Follow Him. Let your habits and your life be rooted in godliness and obedience. Seek after wisdom with all your heart. Walk with your eyes open.
Vs 27 - Don't give in to temptation. Don't get distracted. When you wander off the path, forsake the byways quickly. Run from sin like you would a poisonous snake. Embrace truth, and walk with the knowledge that the path God has set for you - and His timing and His plan - is the absolute best.
See what I mean?
It's all there.
Nice of our Heavenly Father to put it so concisely, wasn't it?
