When Jesus left, He sent the Holy Spirit to abide in us. By doing so He also anointed us through the Holy Spirit to function effectively in life - 1 Jn 2:20. WIthout the anointing of God you cannot accomplish all that God has called you to do. You will be ineffective because what God intends for you to do in life will take more than your abilities to complete.
The anointing to function is the divine enablement endowed on a believer to function beyond his natural abilities. As a believer you have access to the anointing. It has already been made available for you through the Holy Spirit. You must acknowledge it and consciously walk in it. You do this by spendimg time in the Word of God, prayer and fasting. Then you stay sensitive to the promptings of the Holy Spirit; allow Him to lead you and follow His instructions.
The anointing to function is available for every area of your life - family, ministry, career, business, etc - 1 Jn 2:27. The anointing package includes wisdom, strength, favor, etc. There's no need for you to struggle any longer. You have the anointing to function.
