Jesus states that its the love of money,or serving the wrong master,not money in itself,he is also referring to abiding by the authority in place,for him it was the Romans,today its what ever governing body is in charge where you are.
Money is not evil it is the love of it. there is no justification required,but then you already knew that.
Luke 16:13 (NIV) "No servant can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money."
Mat 6:19-21 (TEB) "Do not save riches for yourselves here on earth, where moths and rust destroy, and robbers break in and steal. Instead, save riches for yourselves in heaven, where moths and rust cannot destroy, and robbers cannot break in and steal. For your heart will always be where your riches are."
Mark 10:21-27,31 (Jer) Jesus looked steadily at him and loved him, and he said, "There is one thing you lack. Go and sell everything you own and give to the poor, and you will have treasure in heaven; then come, follow me." But his face fell at these words and he went away sad, for he was a man of great wealth. Jesus looked around and said to his disciples, "How hard it is for those who have riches to enter the kingdom of God!" The disciples were astounded by these words, but Jesus insisted, "My children," he said to them, "how hard it is to enter the kingdom of God! It is easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of God." They were more astonished than ever. "In that case," they said to one another, "who can be saved?" Jesus gazed at them. "For men," he said, "it is impossible, but not for God: because everything is possible for God... Many who are first will be last, and the last first."
Luke 14:33 (RSV) "Whoever of you does not renounce all that he has cannot be my disciple."
Mat 6:24 (NIV) "No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money."
Luke 9:25 (NIV) "What good is it for a man to gain the whole world, yet lose or forfeit his very self?"
Luke 12:29-34 (Phi) "You must not set your heart on what you eat or drink, nor must you live in a state of anxiety. The whole heathen world is busy about getting food and drink, and your Father knows well enough that you need such things. No, set your heart on his kingdom, and your food and drink will come as a matter of course... Sell your possessions and give the money away to those in need. Get yourselves purses that never grow old, inexhaustible treasure in Heaven, where no thief can ever reach it, or moth destroy it. For where your treasure is, you may be certain that your heart will be there too!"
Money is the greatest distraction from God. Every moment that you spend trying to work for money takes you away from seeking God.
But keep trying to justify it, if it makes you feel better about yourself.
