Righteousness shall be the belt of His loins, And faithfulness the belt of His waist. Isaiah 11:5 NKJV
The right spiritual passion is passion, thirst and hunger for the word of God and righteousness.
Constant desire for the will of God, righteousness and obedience will mean that you have put things in the right perspective and focus. Walking in the right focus, order and perspective will lead to bearing fruits even to a hundredfold!
May we always hunger and thirst for righteousness.
