Ephesians 6
"10 Finally, my brethren, be strong in the Lord, and in the power of his might. 11 Put on the whole armour of God , that ye may be able to stand against the wiles of the devil. 12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. 13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. 14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; 15 And your feet shod with the preparation of the gospel of peace; 16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. 17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God: 18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;"
Romans 8
"31 What shall we then say to these things? If God be for us, who can be against us? 32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? 33 Who shall lay any thing to the charge of God's elect? It is God that justifieth. 34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us. 35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. 37 Nay, in all these things we are more than conquerors through him that loved us. 38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, 39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord."
Ephesians 3
"11 According to the eternal purpose which he purposed in Christ Jesus our Lord: 12 In whom we have boldness and access with confidence by the faith of him. 13 Wherefore I desire that ye faint not at my tribulations for you, which is your glory. 14 For this cause I bow my knees unto the Father of our Lord Jesus Christ, 15 Of whom the whole family in heaven and earth is named, 16 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; 17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, 18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height; 19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God. 20 Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us , 21 Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen. "
God's Word will prepare you (the Sword of the Spirit). We just have to spend time committing it to memory and believing it.
