Jesus Christ is worthy of our very best. He wants to be our top priority. One person cannot tell another when she is giving her best. Sacrifice is always personal.
Therefore each of us must determine what is the thing about ourselves, our lives or our situations we value most, and then to always ready and willing to lay it down should the Spirit lead.
God the Father has given us His very best in Jesus Christ our Lord. May we learn to love Him the way He has so loved us!
