If you try something and you fail at it, you try again. That goes the same with sin. As I was online reading the bible and different commentaries, the word "exhort" came up. I didn't really know what it meant so I looked it up and the basic definition to my knowledge is like a warning and/or encouragement depending on how you use it (correct me if I am wrong). The bible says that we should exhort one another daily. From the context around that verse (Hebrew 3:13) it was speaking on how one can drift away from the Word of God unknowingly and by exhorting one another and even your self can be a tool used to help you or a friend not drift away and stay in the Word.
So I challenge you and myself to exhort, exhort, exhort. You never know, your exhortation may help a brother or sister not sin and become deeper in Christ. Then that person can exhort the next and so on.Let people know that God cares for them and that even if you do fail just try even harder to succeed the next time. Stay confident.
