Hello Unconvinced!
How does this sound to you?
You had mentioned that worshipping a deity is a waste of time, what decision would you consider to be wiser between these two choices that you have.
1. Don't waste time worshipping a deity because he may or may not exist.
OR
2. Just simply believing in the existence of God and maybe at the end of your road you finally realize that He was real and then having escaped condemnation just by simply believing!
What do you got to lose but you have everything to gain, so which one would you choose?
God Bless!
