Deuteronomy 28:45, 47 NKJV
[45] “Moreover all these curses shall come upon you and pursue and overtake you, until you are destroyed, because you did not obey the voice of the Lord your God, to keep His commandments and His statutes which He commanded you.
[47] “Because you did not serve the Lord your God with joy and gladness of heart, for the abundance of everything,

Gladness - to do well, do good, act right, act rightly

Matthew 22:37-39 TPT
[37] Jesus answered him, “ ‘Love the Lord your God with every passion of your heart, with all the energy of your being, and with every thought that is within you.’ [38] This is the great and supreme commandment. [39] And the second is like it in importance: ‘You must love your friend in the same way you love yourself.’

I Corinthians 13:4-8 NKJV
[4] Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; [5] does not behave rudely, does not seek its own, is not provoked, thinks no evil; [6] does not rejoice in iniquity, but rejoices in the truth; [7] bears all things, believes all things, hopes all things, endures all things. [8] Love never fails...

If we are not walking in love and dealing with being offended, then we are not serving the Lord with joy and gladness. Not only do you open yourself up for attacks from the enemy but you also hinder your prayers from being answered.

Faith and patience inherit the promises and faith works by love.
