Ephesians 6:17 (NLT) Put on salvation as your helmet and take the sword of the Spirit, which is the word of God.
2 Timothy 2:22-26 (Amplified Bible)
22Shun youthful lusts and flee from them, and aim at and pursue righteousness (all that is virtuous and good, right living, conformity to the will of God in thought, word, and deed); [and aim at and pursue] faith, love, [and] peace (harmony and concord with others) in fellowship with all [Christians], who call upon the Lord out of a pure heart.
23But refuse (shut your mind against, have nothing to do with) trifling (ill-informed, unedifying, stupid) controversies over ignorant questionings, for you know that they foster strife and breed quarrels.
24And the servant of the Lord must not be quarrelsome (fighting and contending). Instead, he must be kindly to everyone and mild-tempered [preserving the bond of peace]; he must be a skilled and suitable teacher, patient and forbearing and willing to suffer wrong.
25He must correct his opponents with courtesy and gentleness, in the hope that God may grant that they will repent and come to know the Truth [that they will perceive and recognize and become accurately acquainted with and acknowledge it],
26And that they may come to their senses [and] escape out of the snare of the devil, having been held captive by him, [henceforth] to do His [God's] will
