According to A Course In Miracles, you do not have to worry about what to say or what to do because he who sent you will direct you. He will direct you!
You don’t have to worry!
He will direct you!
It’s not that he might direct you. He WILL direct you. You do not have to listen though.
A Course In Miracles uses the future tense; he will direct you. Despite time being an illusion, the direction may occur in 1 millionth of a second or in 1 million years. Maybe it is happening right now.
Either way, he will direct you and you don’t have to worry. You can worry if it’s helpful, but you don’t have to! You need do nothing, but you are not required to do nothing.
Follow your heart and Holy Spirit. You will be directed.
