1 Cor. 4:2

Moreover it is required in stewards that one be found faithful.

Matthew 24:45-51

"Who then is a faithful and wise servant, whom his master made ruler over his household, to give them food in due season? [46] Blessed is that servant whom his master, when he comes, will find so doing. [47] Assuredly, I say to you that he will make him ruler over all his goods. [48] But if that evil servant says in his heart, 'My master is delaying his coming,' [49] and begins to beat his fellow servants, and to eat and drink with the drunkards, [50] the master of that servant will come on a day when he is not looking for him and at an hour that he is not aware of, [51] and will cut him in two and appoint him his portion with the hypocrites. There shall be weeping and gnashing of teeth.

Matthew 25:14-30

"For the kingdom of heaven is like a man traveling to a far country, who called his own servants and delivered his goods to them. [15] And to one he gave five talents, to another two, and to another one, to each according to his own ability; and immediately he went on a journey. [16] Then he who had received the five talents went and traded with them, and made another five talents. [17] And likewise he who had received two gained two more also. [18] But he who had received one went and dug in the ground, and hid his lord's money. [19] After a long time the lord of those servants came and settled accounts with them. [20] So he who had received five talents came and brought five other talents, saying, 'Lord, you delivered to me five talents; look, I have gained five more talents besides them.' [21] His lord said to him, 'Well done, good and faithful servant; you were faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.' [22] He also who had received two talents came and said, 'Lord, you delivered to me two talents; look, I have gained two more talents besides them.' [23] His lord said to him, 'Well done, good and faithful servant; you have been faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.' [24] Then he who had received the one talent came and said, 'Lord, I knew you to be a hard man, reaping where you have not sown, and gathering where you have not scattered seed. [25] And I was afraid, and went and hid your talent in the ground. Look, there you have what is yours.' [26] But his lord answered and said to him, 'You wicked and lazy servant, you knew that I reap where I have not sown, and gather where I have not scattered seed. [27] So you ought to have deposited my money with the bankers, and at my coming I would have received back my own with interest. [28] Therefore take the talent from him, and give it to him who has ten talents. [29] For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away. [30] And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.'

2 John 1:8

Look to yourselves, that we do not lose those things we worked for, but that we may receive a full reward.

Psalm 96:7-9

Give to the LORD, O families of the peoples, Give to the LORD glory and strength. [8] Give to the LORD the glory due His name; Bring an offering, and come into His courts. [9] Oh, worship the LORD in the beauty of holiness! Tremble before Him, all the earth.
