feeling selfish and unappreciative

I must not fully appreciate what I have through Christ.
The changes He has made in my life.
The freedom, peace, and confidence that I walk in daily...
not perfectly... is so different than I used to be.

So why don't I share what I know with others who are struggling? People -- loved ones -- who I know are far from God. Why don't I share the mystery of faith, the presence of Christ, the hope of glory? Why do I hold back?

I long for everyone to know Christ.
I want to say with Paul:

We proclaim him, admonishing and teaching everyone with all wisdom, so that we may present everyone perfect in Christ. To this end I labor, struggling with all his energy, which so powerfully works in me.

Colossians 1:28, 29

Is His energy powerfully at work in me? Is it available to me? I think I look for open doors in conversations... but today I feel, I don't know ...selfish... like I must not want to share what I have with someone who might not understand...

Lord, forgive me for missed opportunities, for lack of faith, for not opening my mouth and sharing how You have changed my life. Help me to remember my story and tell others without shame or fear. Teach me how to share my personal experiences with others.
