1 Corinthians 10:23 “All things are lawful,” but not all things are helpful. “All things are lawful,” but not all things build up. What you are doing instead of working may not be wrong, but is it helpful? Is it glorifying to God?
1 Corinthians 10:31 So, whether you eat or drink, or whatever you do, do all to the glory of God. It may seem of fleeting importance, but fully applying yourself to your schoolwork can glorify God if done with the correct attitude.
Ephesians 2:10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them. God has prepared good works for you in advance. Go out and do them--don't procrastinate!
Colossians 3:22-24 Bondservants, obey in everything those who are your earthly masters, not by way of eye-service, as people-pleasers, but with sincerity of heart, fearing the Lord. 23 Whatever you do, work heartily, as for the Lord and not for men, 24 knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ. This could be addressed to students as well. Don't work as for your professors, but as for God!
Ephesians 5:15-17 Look carefully then how you walk, not as unwise but as wise, 16 making the best use of the time, because the days are evil. 17 Therefore do not be foolish, but understand what the will of the Lord is. Honor God with how you use your time.
2 Thessalonians 3:6-15 Now we command you, brothers, in the name of our Lord Jesus Christ, that you keep away from any brother who is walking in idleness and not in accord with the tradition that you received from us. 7 For you yourselves know how you ought to imitate us, because we were not idle when we were with you, 8 nor did we eat anyone's bread without paying for it, but with toil and labor we worked night and day, that we might not be a burden to any of you. 9 It was not because we do not have that right, but to give you in ourselves an example to imitate. 10 For even when we were with you, we would give you this command: If anyone is not willing to work, let him not eat. 11 For we hear that some among you walk in idleness, not busy at work, but busybodies. 12 Now such persons we command and encourage in the Lord Jesus Christ to do their work quietly and to earn their own living.
13 As for you, brothers, do not grow weary in doing good. 14 If anyone does not obey what we say in this letter, take note of that person, and have nothing to do with him, that he may be ashamed. 15 Do not regard him as an enemy, but warn him as a brother. Work is from God. Don't grow weary.
