Go Find Your Own Spirituality
Abraham's primitive spirituality was radically different than Moses' deliverance spirituality. But then Moses' spirituality was radically different than Samuel's prophetic spirituality. And Samuel's spirituality certainly looked a lot different than David's earthy spirituality. And David's spirituality looked a lot different than Jeremiah's sorrowful spirituality. But then Jeremiah's spirituality looked quite a bit different than Peter's Messianic spirituality. And Peter's spirituality looked a lot different than Paul's missional spirituality.
Each one was different. They lived their own spirituality.
Then there are obscure stories such as the one of the man who was using Jesus' name and the disciples asked Jesus if they should stop him. Jesus said that if he isn't against him, then he's for him. The man didn't even have a personal relationship with Jesus and he was just fine.
I'm saying this to encourage you to go and find your own unique spirituality. Whatever it is. It is yours. It must be yours. Don't be afraid.
