My time is short on this forum, so I want to leave with a piece of advice to all Christian posters.
When someone is rude, respond with kindness.
When you feel like making fun of the person you are talking to, or insulting them for being particularly dense, don't do it. It hurts your witness. Be patient. Long suffering.
People are rarely converted by arguments and such. Without love, it doesn't matter if you know everything. You won't be heard.
Remember, you are not The Holy Spirit. You can not save anyone. Your job is to plant seeds. Seeds that you may never see grow. Be content with that.
If you call yourself a Christian, and do not engage with a spirit of love, you are doing more harm than good. It would be better if you worked on yourself before trying to proselytize.
Truly, Christ is best witnessed by someone who walks in the way. Being a good Christian is the best witness.
Have faith in divine judgment. Don't be lead astray by passion or insecurity. Become less so that Christ is magnified.
Will you slip up? It happens. Don't excuse yourself, simply correct course.
Aquire the spirit of peace, and thousands around you will be saved.
