Thank you for your concern, I am emphizing the repentance and believe the gospel especially in our times that some people are not believing in God and the bible.
Maybe later we can use the verse you mentioned above. May God bless you brother @alvinauh
God bless you too, I think it is always best to engage others in a more personal manner. Think just writing like that seems a bit "in your face" to others. Personally, I have led teens at church and the best way is not to dump the word of God on them but just to talk to them and share with them. Ultimately, the choice to accept the Lord is in the hands of those who hear them and we can only plant the seed.
