Eph:6:14 Belt of truth, buckled around your waist. That holds all your armour. The core of it all is the truth of the gospel. Believe in it always. Always be aware of from where you have been called; humbling yourselves. The righteousness of God. That has been imputed upon us. Not by our merit. But by the grace of God. Always binded by the truth. No matter what happens, to stick to the truth. Because He is true.

Finally be strong in the Lord and in His mighty power. Eph:6:10 Be strong. Do not fear. Do not be discouraged. Do not lose heart. Be strong against the schemes of the devil. You may seem weak. But the One who is in you is more powerful than the one who is in the world. Put on the full armour and be strong. Isn't it beautiful to think - God with all His might and power could have just annihilated the devil. But what He chooses to do is to enable His power in weaklings like me, to defeat Him. Resist the devil and he will flee from you. Image courtesy: https://www.vecteezy.com/free-photos/strong-hand
