Be strong (strengthened by your union) in the Lord and in His mighty (great, vast) power. Put on all of God’s (full) armor so that you will be able to stand firm against all strategies (schemes, strategies, tactics, tricks) of the devil. For we are not fighting (struggling, wrestle) against flesh-and-blood enemies (people on earth), but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places (realms). Therefore, put on every piece of God’s (full) armor so you will be able to resist the enemy in the time of evil. Then after the battle (you have finished the whole fight) you will still be standing firm (stand your ground). Stand (strong) your ground (firm), putting on the belt of truth (buckled or tied around your waist) and the body armor (breastplate) of God’s righteousness (right living, integrity and morality on your chest). For shoes (your feet), put on (wear) the peace that comes from the Good News so that you will be fully prepared (stand strong). In addition to all of these (in every situation), hold (take) up the shield of faith to stop (extinguish, quench) the fiery (flaming, burning) arrows of the devil. Put on (accept God’s) salvation as your helmet, and take the sword of the Spirit, which is the Word of God (God’s Word). Pray in the Spirit at all times (always) and on every occasion (with all kinds of prayers, supplications, petitions and requests asking for everything you need). Stay alert and (always) be persistent (with all perseverance, intercession and never give up) in your prayers for all believers (God’s people, saints) everywhere. Ephesians 6:10-18 (NLT).
In our daily lives, we all face struggles and attacks from evil (see 1 Peter 5:8). God tells us the only way to fight back against evil is through faithfully depending on His strength, weapons, and power as our Commander in Chief. The Apostle Paul assures us that God's mighty weapons — constant prayer, faith (trust), truth, hope, love, God's Word, the Holy Spirit — are powerful and effective to defeat evil (see 2 Corinthians 10:1-6; Ephesians 6:13-18)!
Our God is strong and mighty. Our strength comes from wholehearted union with God (Father, Son – Jesus Christ, and Holy Spirit) (read John 14, 15 and 16). God is the source of spiritual power. So use every piece of God’s weapons to resist and fight evil. God's Word is an essential weapon and the only offensive weapon. God blesses His Word found in the Holy Bible (Isaiah 55:8–11). Jesus Christ used this God’s Word in the wilderness to defeat evil attacks (see Matthew 4:4–10, Luke 4:1-13). God’s Word is living, powerful, effective, and instructive (Hebrews 4:12; 2 Timothy 3:16-17).
In the same way, constant and daily prayer is necessary in this ongoing warfare (see 1 Thessalonians 5:17). Without prayer, God’s armor cannot achieve victory. Prayer keeps the lines of communication open with God, our Commander in Chief (see Joshua 5:13–15; Hebrews 2:10). As believers, we must keep in constant communication with God for directions and encouragement. Believers are to make prayer a way of life for themselves and for all believers everywhere. The Apostle Paul teaches that we are not to pray not just for ourselves but also for all saints (believers of Jesus Christ) because spiritual combat with evil is both an individual and corporate matter (James 5:16).
