What does the Bible say about salvation being free?

Isaiah 55 invites all who are thirsty to come and receive God's blessings without charge. This profound invitation underscores the nature of salvation as a free gift from God, available to all who acknowledge their need and come in faith. The very essence of the Gospel is that it is unearned, gifted by God's grace, which frees us from the burden of works and merit in our pursuit of salvation. The Bible repeatedly emphasizes that true salvation cannot be bought or earned but is graciously bestowed by God through faith in Jesus Christ.
