"And [Jesus] was handed the book of the prophet Isaiah. And when He had opened the book, He found the place where it was written:
    “The Spirit of the Lord is upon Me,
    Because He has anointed Me
    To preach the gospel to the poor;
    He has sent Me to heal the brokenhearted,
    To proclaim liberty to the captives
    And recovery of sight to the blind,
    To set at liberty those who are oppressed;
    To proclaim the acceptable year of the Lord.” Luke 4:17-19

"Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty. But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord." 2 Corinthians 3:17-18

"...if the Son makes you free, you shall be free indeed." John 8:36

Liberty to follow God way, not license to sin:

"For though I am free from all men, I have made myself a servant to all, that I might win the more; and to the Jews I became as a Jew, that I might win Jews; to those who are under the law, as under the law, that I might win those who are under the law; to those who are without law, as without law (not being without law toward God, but under law toward Christ), that I might win those who are without law; to the weak I became as weak, that I might win the weak. I have become all things to all men, that I might by all means save some. Now this I do for the gospel’s sake, that I may be partaker of it with you." 1 Corinthians  9:19-23

"All things are lawful for me, but all things are not helpful. All things are lawful for me, but I will not be brought under the power of any." 1 Corinthians 6:12

God's liberty refers to the spiritual freedom we have in His Kingdom, not to the physical or earthly "freedoms" of the world. Walking with Jesus, we may be hated, imprisoned and killed for our faith, but such assaults do not infringe on the liberty we enjoy in Christ!

"Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage." Galatians 5:1

 

"Therefore submit yourselves to every ordinance of man for the Lord’s sake, whether to the king as supreme, or to governors, as to those who are sent by him for the punishment of evildoers and for the praise of those who do good. For this is the will of God, that by doing good you may put to silence the ignorance of foolish men as free, yet not using liberty as a cloak for vice, but as bondservants of God." 1 Peter 2:13-16

"...the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God." Romans 8:20-21
