Dear Sister @existential mabel... I'll keep this short and simple... it's always interesting to read and see certain peoples beliefs one way or the other especially in these forums (especially when 'some' get a bit carried away ?... just saying ?)...
Anyhow, at the end of the day, 'you' continue to live Jesus in your life, as you walk with Him, the Holy Spirit will guide you and give you the words to speak to whomever the Father puts on your path. There is no text book on sharing Jesus, other then your life, regardless if it is to non-christian/ believers alike...
1 Corinthians 16:13 New Living Translation (NLT)
13 Be on guard. Stand firm in the faith. Be courageous.[a] Be strong.
