If "you" think you can fix what is lacking in your relationship with a spouse, child or friend, you are sadly mistaken. Yes, change may be required on your part to be more loving, understanding and compassionate, but ONLY through "true" change will the relationship be FIXED. What is "true" change? True change can only come through our Lord and Savior Jesus Christ! Turn it over to God, then start praying! Pray, "specifically" for that friend, child or spouse, and for God's guidance in the relationship moving forward.
What may seem like an impossible situation to you, is where God does His BEST work!
"Jesus looked at them and said, "With man this is impossible, but with God all things are possible." (Matthew 19:26)
