Yes Jesus has strong words about lust.
“You have heard it said of old, ‘You shall not commit adultery.’ But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.” (Matthew 5:27-29)
But we are free from sin because of Jesus’s sacrifice. We are free from being slaves to sin but we not yet free from temptation in this world. (Isn’t the devil so desperate and annoying, but he is defeated!) But we can overcome all through submitting to Christ!
“Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him.” (James 1:12)
“For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every thing that exalts itself against the knowledge of God,
bringing every thought into captivity to the obedience of Christ.”
(2 Corinthians 10:4-5)
And the Holy Spirit helps us!
“Therefore, brethren, we are debtors – not to the flesh, to live according to the flesh. For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live.” (Romans 8:12-13)
