Titus 2:11-14
For the grace of God has appeared, bringing salvation for all people training us to renounce ungodliness and wordly passions, and to live self-controlled, upright, and godly lives in this present age, waiting for our blessed hope, the appearning of the glory of our great God and Savior Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works.
Matthew 24:14
And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.
2 Peter 3:11-12
Since all these things are thus to be dissolved, what sort of people ought you to be in lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be set on fire and dissolved, and the heavenly bodies will melt as they burn!
