I preached a sermon on Christmas morning on the following passage from 2 Corinthians 6:
11 Our mouth has spoken freely to you, O Corinthians, our heart is opened wide. 12 You are not restrained by us, but you are restrained in your own affections. 13 Now in a like exchange-I speak as to children-open wide to us also.
God has opened His heart toward you through His Son, Jesus Christ. Open your heart to Him.
