2 Thessalonians 1:8
in flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ

Acts 2:37-38
Authorized (King James) Version
37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? 38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
