Scripture
2 Timothy 1:7 (ESV)
For God gave us a spirit not of fear but of power and love and self-control.
Consider
When someone harms us with a thoughtless, selfish, or malicious act, we may instinctively respond by erecting an emotional barrier. This barrier gives us time to sort out what has happened, to decide what it means to us, and to determine whether we will simply let the offense go and take the barrier down or to keep the barrier in place.
Especially in cases where our trust has been betrayed, this barrier can harden into a stubborn wall of unforgiveness.
