Sinners are redeemed from all iniquity/disobedience and made into believers, obedient Titus 2:14
14 Who gave himself for us
, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
Unbelief is iniquity
The word redeem here is the greek word lytroō and one of its features :
- to release on receipt of ransom
- to redeem, liberate by payment of ransom
- to liberate
- to cause to be released to one's self by payment of a ransom
- to redeem
- to deliver: from evils of every kind, internal and external
It delivers those for whom Christ died from internal evils, like unbelief, it liberates
