“I give you a new command: Love one another. Just as I have loved you, you are also to love one another." (John 13:34)
I believe God has put us on earth to love one another, to care for one another, to help one another. And to proclaim His Good News.
Your mission, should you choose to accept it, is to love and help other people, and to proclaim your God to all people.
Not many people accept this mission. Some accept and do the first part; but ignore the second part for various reasons. Perhaps they don't feel up to it, (remember Moses?), or perhaps because they themselves don't believe in God so they can hardly proclaim His Good News to others.
Whatever we do in life, we have the opportunity to help others. You're a doctor - you're helping others. A lawyer, a teacher, a shop assistant, whatever you are in life - you are there to help others. Even a smile to a stranger, or a "hello" or "good morning", is helping others. We never know, but we may be the only ray of sunshine in that person's life that day.
We are always an example to others. People see us and we are either a good example for others to follow; or a bad example for others to avoid copying.
Even writing a blog, or being on social media is helping others; and proclaiming God's news to others.
Our blog may be about gardening, cooking, or whatever; it is an opportunity, (if we want it to be), to proclaim God's news to others.
It may be vanity on my part, but I do check the statistics regularly.
