"Freely ye have received, freely give." (Matthew 10:8b)
A parsimonious position
Sometimes it's hard for me to go one further and ensure the person with whom I'm interacting doesn't get a stunted and stinted version of my best self. If I take a second and hark back to the beautiful ways God has interacted with and filled me up, there's no reason for me to not be giving. Actually, the only reason I could cite may not even be a valid one. When I, by continuing to be present for whomever God brings across my path, give of my time, attention, whatever, I could be giving myself away. As in, revealing unprotected aspects of myself that aren't in keeping with the image I present to the world. Hmm... Let me back up a bit.
"And you, being dead in your sins and the uncircumcision of your flesh, hath He quickened together with Him, having forgiven you all trespasses." (Colossians 2:13)
"For ye are dead, and your life is hid with Christ in God." (Colossians 3:3)
This is from where we start. Firstly, we can't give what we don't have and yet, as the Lord has effectively "freely given us all things." (Romans 8:32b), we don't have to worry about running out. God is the supply and the demand is heavy. But I'm worried about what? About giving up something I'm not likely going to receive in return. Something like a piece of my soul or a stretch of my future I'm not gonna get back. This is wrong.
"But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light." (Ephesians 5:13)
There's a difference between the searching light of the Holy Spirit and any inwardly directed scrutiny borne out of what those around (whether in body or in memory), think of you. I believe God shines His light into deeper and deeper depths and will continue to do so until we go home. But any fear that arises from opening ourselves up and letting God flow through us to the neglect of those in need, needs to go. As God holds us and every aspect of our life in balance, the beautiful things in your life can be shared with whomever the Holy Spirit leads you to.
Love, joy, peace, etc. Let it burn inside and roil around a bit. And then give it out. God bless you.
