When you send an offering to your man of God, don’t think you’re enriching him, because you couldn’t, even if you tried. The anointing upon him is not for his benefit but for your benefit!
God instructed the children of Israel to bring all their offerings and sacrifices to the priests so they could connect to the anointing. This was the anointing that caused them to remain prosperous in all they did. In the same way today, your prosperity is in your man of God.
The Lord used the term ‘forever’ in Numbers 18:8 because of some skeptics that would think that the ordinance was restricted to those folks who lived under the Old Covenant.
Paul asked in 1 Corinthians 12:29-30, “Are all apostles? are all prophets? Are all teachers? are all workers of miracles? Have all the gifts of healing? do all speak with tongues? do all interpret?” The obvious answer is “No!” Why? It’s because God has set gifts – apostles, prophets, evangelists, pastor and teachers – in the Church “For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ” (Ephesians 4:12). So you see, God has given priests to minister to the nation of priests (the Church). Remember that according to Revelation 1:6 we’ve all been called into the priesthood ministry.
God uses their offerings to connect His people to the anointing. Did you ever read the book of first Kings about Elijah and the widow of Zarephath? When you study it by yourself in 1 Kings 17:9-16, you will discover that the woman’s situation changed when she connected to the anointing on the prophet by what she gave him. You don’t need any hands laid on you to prosper; learn to connect yourself to the anointing in the appropriate manner and you will be amazed at the result.
