It's not enough to be skilled with words or know the Bible. It takes the anointing of the Holy Spirit to press the truths of God into men's hearts.
Ask God to take the words of the preacher and make them real as only He can. When God speaks, things are created, hearts are changed.
1Cor. 2:4 (NIV) My message and my preaching were not with wise and persuasive words, but with a demonstration of the Spirit's power, so that your faith might not rest on men's wisdom, but on God's power.
Lord, You have the name that is above all names. You are Lord forever and there is no one who can challenge Your authority and power. You rule forever and ever, and there is no end to Your Kingdom.
Lord, I ask that You would anoint Ishkashimi of Afghanistan
as they preach and teach. Bring forth a demonstration of Your power to those who hear. Challenge the spirits of that region with Your presence, Lord. You are the Lord of all the earth. Let Your name be exalted over every spirit of darkness within the hearing of Ishkashimi of Afghanistan
's preaching. Manifest Your presence Lord, and magnify the name of Your son Jesus.
