In general, the concept of trading is thought of as giving something in exchange for something else. As a believer the most important place of exchange, or trade, is at the cross. By way of the cross, and the body and blood of Jesus, we exchange our unrighteousness for His righteousness and eternal life.
Sometimes at meetings you may see people dropping money into baskets. They are moved in their spirit by something that they hear, so they honor Yahweh, and the revelation, by giving something of value in exchange. Essentially, they are trading into revelation, not only for themselves, but for their future generations as well. By faith, they are believing that these seeds of revelation will expand and come to maturity as they honor them and hold them in their heart.
Many people have seen tremendous fruit and breakthrough in their lives by walking in this type of faith.
