We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him (1 John 5:18). If you’re going to walk closely with the Lord, you must guard or “keep” yourself. We must be vigilant to continue to do the things necessary to keep our walk with the Father strong and robust. The writer of Hebrews said it well: Therefore we must give the more earnest heed to the things we have heard, lest we drift away (Hebrews 2:1). Lest we drift away could be translated run out as leaking vessels. We have a leaking problem! It’s so easy to become slack and not be diligent in the things of God. To be a strong believer today, I must continue to do the things I’ve done in the past to remain strong. Too many believers become slack and let down their defenses and drift from the place of safety in God. Therefore let anyone who thinks he stands [who feels sure that he has a steadfast mind and is standing firm], take heed lest he fall [into sin]( 1 Corinthians 10:12 – Amplified). Keep guard over yourselves, so that you may not lose the results of your good deeds, but may receive back a full reward (2 John 8 – Weymouth) During their wilderness wanderings, God graciously gave the Israelites daily food called manna to sustain them physically. The manna would appear on the ground at night and they were to pick it up the next morning before the dew dried. And they could only get a one day supply with the exception of the day before Sabbath, where they could pick up an extra day’s supply for the Sabbath rest. Some lazy Israelites tried to pick up an extra day’s supply on a week day, and the manna bread worms and begin to stink! You see, we can’t live on yesterday’s time with God, and we can’t depend on what has happened in our past to sustain us today in God. The blessings of yesterday won’t sustain you in the challenges of today! We must maintain a real time fellowship with the Father in the Word and in prayer every day. Smith Wigglesworth said: Pay attention to life’s inflow. Outward service will dwindle if inward energies are not renewed. I’ve seen so many believers over the years become satisfied and slack! And I’ve watched as the spiritual fire and zeal slowly left their lives. Don’t let that happen to you. Don’t become complacent and think that you’re safe. Take heed! Within myself I keep this thought: just because I was spiritually strong yesterday, and just because I have a record of God using me in the past, is no indication that I will be strong today. I could fall away unless I keep doing the things necessary to stay close to my Father. Honest assessment guards against slackness. Ask yourself the following questions. Do I take time each day to “feed” on the Word? Do I maintain a daily private life of prayer and communion with the Father? Do I judge sin in my life immediately? Or do I just let it go and think that the Father understands me and my “weakness?” Am I as close to the Lord now as I was a year ago? Are my personal habits pure? Do I guard my thoughts and refuse to think on unseemly things? Do I readily forgive all offenses? Am I selfish? Do I spend my time wisely? A wise believer keeps careful guard over himself. Keep yourself. Give yourself a regular spiritual checkup.
