How innocent are we?

I want to challenge myself and anyone who reads this. I have been reading through Acts and I keep going over and over Acts 20. There are few verses that keep piercing me, but verse 26 is what really gets me,

Therefore I testify to you this day that I am innocent of everyone's blood...then Paul goes on to say in verse 27....for I did not shrink back from declaring to you the whole plan of God.

How many times have we felt The Spirit leading us to go talk with a person and ignore it? I know I am guilty of this WAY to many times. I will strive each day to make Christs name known. Dr. Foshee said in his Contemporary Evangelism class, "faithfulness to share is our measure of success. God holds us accountable for obedience not perfection." We are not going to have success every time, we are going to be rejected, but atleast we know we are innocent of that persons blood. May I never hold back the whole plan of God.
