Your wording is problematic.
You can’t think *I want to follow Christ but I must wait for God to give me the desire to*, because the very fact that you had the thought means that God has already given you the desire to.
The person who is not being drawn by God doesn’t even entertain the thought of wanting to follow Christ.
So there’s no waiting to be given the desire.
Waiting implies that the desire is already there, and if it’s there, it’s because God already gave it to you.
Thank you for your clarification.
