There are many of us, me included, who need to learn how to be more gentle on ourselves where we don't meet our own standards. Obsessing about a meeting or presentation that could have gone better, beating ourselves up for an idea that failed. Or for believers, being willing to forgive ourselves and let it be when God has forgiven us instead of continuing to resaw the sawdust in our own minds leaving us living in guilt instead of the freedom we have through forgiveness. Satan loves to keep us from experiencing the freedom we have in Christ. He came to redeem and forgive and give us freedom.
Reflect on how Jesus treats us. "Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light. (Matthew 11:28-30)."
If Jesus is gentle with us why are we not gentle with ourselves? If he wants to give us rest for our weary and sinful souls why do we not live in that rest? If he wants to grant us freedom, why would we not live in that freedom? In essence when we do not forgive ourselves when He has we are not fully accepting his gift of forgiveness. And, living in guilt and shame leaves us open to the attack of the evil one in a special way.
All of us live with regrets and past failures. Jesus came to free us from that through His redemption and forgiveness. We are not perfect and will not be till we see Him. Part of followership of Jesus is accepting His grace in our lives and living in grace rather than in guilt and shame. Which are you living in today?
