The greatest service we can do towards God is to love Him.
Even if you have the faith to move mountains and the gift of prophecy, and understand all mysteries, but do not have a heart filled to overflowing with love for God and for the people around you; you are nothing.
The bond of love is the bond of perfection; the witness of the Father's Spirit with your spirit that you are a child of God; the evidence that the grace of Jesus Christ has been applied to your life.
If we minister to God's sheep and God's lambs without love we divide the Body of Christ; but if we minister with hearts overflowing with love we unite the Body of Christ.
Blessed are the peacemakers.
