Why all should work?

Christ died that they might work:

2 Corinthians 5:15-21

15 And he died for all, that those who live should no longer live for themselves but for him who died for them and was raised again.

16 So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer.

17 Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!

18 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation:

19 that God was reconciling the world to himself in Christ, not counting men's sins against them. And he has committed to us the message of reconciliation.

20 We are therefore Christ's ambassadors, as though God were making his appeal through us. We implore you on Christ's behalf: Be reconciled to God.

21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.

Titus 2:14

Who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good.

Scripture were given to qualify them for work:

2 Timothy 3:16-17

16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,

17 so that the man of God may be thoroughly equipped for every good work.
