Remain Spiritually Alert
Ephesians 6:12 Updated American standard version (UASV)
12 For our wrestling is not against flesh and blood, but against the rulers, against the powers, against the world-rulers of this darkness, against the wicked spirit forces in the heavenly places.
 Or struggle
When we initially became a well-grounded Christian, we (1) obtained a real, broad knowledge of Bible truth (1 Tim. 2:3-4), (2) put faith in the things we had learned (Heb. 11:6), we (3) repented of our sins (Acts 17:30-31), and we (4) turned around in our course of life. (Acts 3:19); (5) Then, our love for God moved us to dedicate ourselves to Christ. (Matt. 16:24; 22:37) (6) Finally, baptism. (Matt. 28:19-20; Mark 1:9-10; Acts 8:36) Since those initial days, we have evidenced for years that we are resolute in keeping our heart complete toward God. However, we must keep in mind that Satan has not given up on us. Satan is bent on finding a way into our figurative heart. Obviously, he may understand that we will not simply abandon God suddenly and unexpectedly. Therefore, he craftily employs this wicked world and those within it in an effort to weaken our heartfelt zeal for God gradually. (Mark 4:18, 19) Why has that method of Satan been so effective for millions of God’s people? Because if our zeal for God is weakened is weakened so gradually, we will not be aware of it. Yes, the effects of Satan’s world may cause our zeal to diminish little by little. If that occurs, Satan has succeeded in decreasing our heartfelt zeal for God in our personal Bible study, Christian meetings, how much effort we put into sharing the Gospel, our prayer life, and so on. If we do not remain alert, we may not even notice this gradual change. – Matthew 24:42; 1 Peter 5:8.
