Wisdom in the world or wisdom of God

Luke 16:8
And his lord was pleased with the false servant, because he had been wise; for the sons of this world are wiser in relation to their generation than the sons of light.

Have faith in the Lord your God

2 Chronicles 20:20
And early in the morning they got up and went out to the waste land of Tekoa: and when they were going out, Jehoshaphat took his station and said to them, Give ear to me, O Judah and you people of Jerusalem: have faith in the Lord your God and you will be safe; have faith in his prophets and all will go well for you.

Christian life is a warfare

Ephesians 6:11
Take up God’s instruments of war, so that you may be able to keep your position against all the deceits of the Evil One.

Ephesians 6:12
For our fight is not against flesh and blood, but against authorities and powers, against the world-rulers of this dark night, against the spirits of evil in the heavens.

1)Eph 6:13 For this reason take up all the arms of God, so that you may be able to be strong in the evil day, and, having done all, to keep your place.
Eph 6:14 Take your place, then, having your body clothed with the true word, and having put on the breastplate of righteousness;
Eph 6:15 Be ready with the good news of peace as shoes on your feet;
Eph 6:16 And most of all, using faith as a cover to keep off all the flaming arrows of the Evil One.
Eph 6:17 And take salvation for your head-dress and the sword of the Spirit, which is the word of God:
Eph 6:18 With prayers and deep desires, making requests at all times in the Spirit, and keeping watch, with strong purpose, in prayer for all the saints,
Eph 6:19 And for me, that words may be given to me in the opening of my mouth, to make clear without fear the secret of the good news,
Eph 6:20 For which I am a representative in chains, and that I may say without fear the things which it is right for me to say.
