1 Corinthians 13:4-7 English Standard Version
4 Love is patient and kind; love does not envy or boast; it is not arrogant 5 or rude. It does not insist on its own way; it is not irritable or resentful;[a] 6 it does not rejoice at wrongdoing, but rejoices with the truth. 7 Love bears all things, believes all things, hopes all things, endures all things.
Footnote a: Greek irritable and does not count up wrongdoing
Pondering the issue of insistence, it is possible that one source of an insistent attitude may be driven by perceived neglect. By replacing counting up wrongdoings with resentful we have replaced the source of the attitude with the resulting attitude.
People who keep score will always perceive that they are owed recompense. When they do not receive it the score goes up and the attitude becomes more insistent.
Life owes us nothing but death.
That is an extremely difficult comment and can only be fully appreciated in the character and quality of God’s mercy and grace. Neither are earned. They are free gifts from God come with the additional benefit of agape love, having found them in the sacrificial works of Christ on the Cross. The abiding love of Christ is this love spoken of in 1 Corinthians 13. It abides in us and can only shine through our flesh if it is allowed to manifest itself by the changing of our hearts and minds.
The mind reflects the change of heart. Sadly the mind cannot change the heart. It works the other way around. Those of us who exhibit attitudes that are insistent, irritable and resentful are in need of heart change.
Psalm 119:11 English Standard Version (ESV) I have stored up your word in my heart, that I might not sin against you.
While His Word may be in their memory, they have not been taken to heart.
