Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.
Do not labor for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal."
But don’t be so concerned about perishable things like food. Spend your energy seeking the eternal life that the Son of Man can give you. For God the Father has given me the seal of his approval.”
