27 "Stop continuously working or doing business for the food which is continuously disintegrating of itself (loosing itself away; destroying itself),
but rather [
for]
the Food continuously remaining (abiding; dwelling)
into eonian Life (life originating from, existing in, having the characteristics and qualities of, the Age; age-enduring and eon-lasting life)
which the Son of the Man (of Humanity; of the human; of mankind; or: = the Human Being)
will continue giving to you (or: in you; for you)
folks, for This One (or: This Man)
Father God seals (or: for God, the Father, put [His] seal [showing ownership and/or approval and/or authority] upon a person [doing] this; or: you see, this One the Father sealed: God).
"
28 Then they said to Him, "What should we be habitually doing, so that we would be habitually working God’s works (or: actions having the character of God; or: the deeds which have their source in God; or: = the things God wants us to do)?
"
29 Jesus considered and answered, saying to them, "This is God’s work (the work whose source is God):
that you folks would continuously trust and progressively believe into that One whom He sends forth with a mission (or: into the One Whom That One sent forth as an Emissary).
"
