Hands on the plough

As I was reading this book last night, I was hung up at the point in the book when F.B. discusses where Jesus is talking with the ones that want to follow but have other things to do before they go. It was convicting to me because I find myself relating to them. I want to do His will but on my terms, so I'm stuck in confusion on what I think. I feel that I get too pushy with myself in serving, wanting to pick and choose where,when and how I want to. I pray for patience in just letting God be God. I'm afraid I'm letting opportunities and blessings pass me by because I'm worried too much about how I want to please God.
