As a Christian - I know how true that quote is ("Comparison is the thief of joy").
As an imperfect human - and more so as a woman -
I know how hard it is to prevent myself from comparing.
The bible even reminds us - on NUMEROUS occasions - to not compare ourselves to others in this world; one of my favourite verses being Romans 12:2 (MSG):
Embracing what God does for you is the best thing you can do for him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.
But I am constantly trying to remind myself this in my every day life. Not just with myself. But with my experiences, my opportunities, with those who surround me (or whom I chose to surround myself with), etc.
My walks - my journey's - my relationships, friendships, encounters, career paths, boss's (or potential), opportunities, etc. It's not just a matter of comparing myself when I look in the mirror - but a matter of comparing myself/my 'realities' to everything else that then 'becomes'.
While this is short and brief - I still felt the need to remind myself (and others) - to remember - not to compare.
But rather to TRUST - and more so - be humbled - enough to know that G-d has your best interest at hand. And the only interest at hand is HIS interest. And we are called to trust in that.
Here's to trusting in G-d's interest!
