Jesus once said this way “He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.” (John 7:38). The rivers He was referring to here is the Holy Spirit and the effects He produces in the life of a believer – ie the “fruits”
What do these fruits look like? Galatians 5:22-23 says, “the fruit of the spirit is love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, temperance.” This fruit is the product of the Holy Spirit, not our effort. They will flow as we conform our thinking to God’s Word.
Our spirit always has these attributes regardless of what we feel in our emotions. Failure to understand this has caused many Christians to think they would be hypocrites to express a “fruit” like joy when in truth they feel something to the contrary. However, we need to understand that it’s only our soulish part that gets these “feelings”. Our spirit is always bearing the fruit of “love, joy, peace, etc.”
For a person who is seeking to walk in the Spirit, it is actually hypocritical to let our soulish emotions dominate our spiritual emotions. The truth is, our spirit is never depressed, just our soul. Those who understand this have the choice of letting their soul depress them or letting the Holy Spirit, through their born-again spirit, release the joy and peace spoken of here.
The “fruit” is not produced by the believer, but by the Holy Spirit, as we live in union with Him. Our part is to yield and trust; God’s part is to produce the fruit.
