Try your hardest to develop a stable Christian character.

2 Peter 1:5-11

5 Because God has done all that, by trying very hard, make sure that you not only believe in Christ, but that you are also living morally good lives. And make sure that you are not only living morally good lives, but that you also know what God desires (OR, behave wisely). 6 And make sure that you not only know what God desires (OR, behave wisely), but that you also control what you say and do. And make sure that you not only control what you say and do, but that you are also steadfast/patient. And make sure that you are not only ◄steadfast/patient when you suffer►, but that you are also godly. 7 And make sure that you not only ◄are godly/live in a way that pleases God►, but that you also have a concern for your fellow believers, as brothers and sisters ought to have for each other. And make sure that you not only have a concern for your fellow believers, but that you also love others. 8 If you do these things, and if you do them more and more, that demonstrates that knowing our Lord Jesus Christ ◄is very effective/produces good results► [LIT] in your lives. 9 If these qualities are not present in people, it means they are not aware that these things are important, just like a blind person is not aware of what is around him. They think only about earthly matters, just like [MET] a shortsighted person sees clearly only things that are near. It seems that they have forgotten that God has forgiven them for their former sinful lives. 10 Instead of acting like those people, try to confirm/prove by the way you conduct your lives that you are among those whom God has chosen [DOU] to be his people. If you do that, you will certainly never become separated from God, 11 and God will very wholeheartedly welcome you into the place where our Lord and Savior Jesus Christ will rule his people forever.
