James 5:12 Above all, my brothers and sisters, do not swear—not by heaven or by earth or by anything else. All you need to say is a simple “Yes” or “No.” Otherwise you will be condemned.
Be devoted, complete and mature. Godly in mind and character. We will improve as Christians. Christ calls each one of us as His disciples and citizen of His kingdom. Let's make a difference.
Jonah 4:1-3 But Jonah was greatly displeased and became angry. He prayed to the LORD, "O LORD, is this not what I said when I was still at home? That is why I was so quick to flee to Tarshish. I knew that you are gracious and compassionate God, slow to anger and abounding in love, a God who relents from sending calamity. Now O Lord, take away my life, for it is better for me to die than to live. But O Lord take away my life, for it is better for me to dies than to live." But the LORD replied, "Have you any right to be angry?"At this moment Jonah finally obeyed God to go to the city of Ninevah and proclaim the message to them. As a result people of Nineveh repented from their sins. However, Jonah was not pleased and so upset because he saw those people (worse sinners) turning from their wicked ways, despite of the fact that he was the one who preached the Word of God to them.
For us, we should rejoice when someone resented and receive Jesus Christ as their Lord and Savior. Because remember, we too are sinners saved by His GRACE.
