I am fully convinced, my dear brothers and sisters, that you are full of goodness. You know these things so well you can teach each other all about them. Romans 15:14

Be careful then, dear brothers and sisters. Make sure that your own hearts are not evil and unbelieving, turning you away from the living God. You must warn each other every day, while it is still “today,” so that none of you will be deceived by sin and hardened against God. Hebrews 3
