I'm sorry.

Two little words that can form one huge lump in our throats when it's time to say them.

JOTSC,
When you have hurt someone and you know it, either with your words or your actions, the very best thing you can do is to genuinely acknowledge your error and sincerely apologize. Especially when you hurt someone you love.

Your pride might make this difficult to do. Keep your pride in check. Swallow that monster. Eliminate it as much as you possibly can. Empty yourself of it. It can ruin your relationships.
Proverbs 11:2
When pride comes, then comes shame; But with the humble is wisdom.

Be certain that you will make mistakes with your loved ones. You will let your mouths run. You will ignore what you should have acknowledged. You will acknowledge what you should have ignored. Things happen between people. We all make errors in judgement. Don't ever act like it is beneath you to make mistakes or to have weak moments. It is not beneath you, it is part of life. If you are aware of this, you won't be so shocked when you have offended, and must make amends.

Keeping your conscience as clear as possible with the people in your lives will do wonders for you, for them and for your relationship with God. Whether you admit when you fumble or not, He knows. You might as well fess up. You will make it easier for those that love you, and in turn your life will be enriched.

True growth and maturity will not happen without a bit of reflection, and willingness to see where you have fallen short. It takes a man or woman of integrity to own up to your humanness, and honestly repent. Repent to God first, then apologize to your beloveds, your co-workers, your acquaintances, strangers on the street or whomever necessary. This is an integral part of clean-heart living, and will enrich your ability to love well. Thank you, I love you.

1 John 1:9
If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
