From what I've read, the word translated 'lust' in the New Testament does not always refer to sexual lust. Here are some verses that use the word.
Mark 4:19
And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful.
John 8:44
Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Romans 6:12
Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
Romans 7:7
What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
Ephesians 2:3
Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
1 Timothy 6:9
But they that will be rich fall into temptation and a snare, and into many foolish and hurtful lusts, which drown men in destruction and perdition.
James 4:2
Ye lust, and have not: ye kill, and desire to have, and cannot obtain: ye fight and war, yet ye have not, because ye ask not.
1 John 2:16
For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
1 John 2:17
And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
