Uncondional love means to love under ALL conditions. It means to love your kids and respond WITH LOVE when they fall short of your expectations. To respond in any way less than that would mean that you are living within your own expectations of perfections. AND YOU KNOW YOU ARE NOT. Share some of that understanding and grace that has been so kindly given to you by God. Love them where you find them and COVER them. Being a parent doesnt mean you should torment your children by placing expectations on them that YOU as a grown up cannot even neet. Love them love them love them. Speak to them with wisdom and with grace….you can do this, just model your Father.
