The Prophet Joel in the Old Testament foretold what would happen in the lives of God’s people when they receive the Holy Spirit: they’ll prophesy; meaning they’ll speak words of power. In other words, what they say will come to pass. When you’re filled with the Holy Spirit, your words cease to be words of men; they become anointed with power.
When the Spirit of God is working in you and you’re overflowing with His fullness, you won’t need to try to muster boldness to say or do things. Whenever you open your mouth to speak, you’ll speak words that are divinely inspired, not idle or inoperative words.
No wonder the Lord Jesus, in Mark 11:23 said you shall have what you say. That’s because the words you speak as one who’s born again are words of power. Therefore, take time to prophecy about your day; use your tongue to order the circumstances of your life aright; speak words of power everyday.
As you speak or confess God’s Word, the anointing of God’s Spirit wells up strongly within you and the words you speak go forth as the sword of the Spirit.
