Medjugorje: Our Lady tells you how to live in joy

Message dated August 10, 1984
Dear children! When you start a day with prayer, with inner recollection and with love in your heart, when you are at peace with everyone, that day will be full of joy for you. But when you are sad, your day will also be sad. So always be in joy! Be as joyful as possible and you will see that your days will be happy too!
Some passages from the Bible that can help us understand this message.
Tobias 12,8-12
Good thing is prayer with fasting and almsgiving with justice. Better the little with justice than wealth with injustice. It is better to give alms than to put aside gold. Begging saves from death and purifies from all sin. Those who give alms will enjoy long life. Those who commit sin and injustice are enemies of their lives. I want to show you the whole truth, without hiding anything: I have already taught you that it is good to hide the king's secret, while it is glorious to reveal the works of God. Know therefore that, when you and Sara were in prayer, I would present the witness of your prayer before the glory of the Lord. So even when you buried the dead.
Proverbs 15,25-33
The Lord tears down the house of the proud and makes the widow's boundaries firm. Evil thoughts are abominable to the Lord, but benevolent words are appreciated. Whoever is greedy for dishonest earnings upsets his home; but whoever detests gifts will live. The mind of the righteous meditates before answering, the mouth of the wicked expresses wickedness. The Lord is far from the wicked, but he listens to the prayers of the righteous. A luminous look gladdens the heart; happy news revives the bones. The ear that listens to a salutary rebuke will have its home in the midst of the wise. Whoever refuses the correction despises himself, who listens to the rebuke acquires sense. Fear of God is a school of wisdom, before glory there is humility.
1 Chronicles 22,7-13
David said to Solomon: “My son, I had decided to build a temple in the name of the Lord my God. But this word of the Lord was addressed to me: You have shed too much blood and made great wars; therefore you will not build the temple in my name, because you have spilled too much blood on the earth before me. Behold, a son will be born to you, who will be a man of peace; I will grant him peace of mind from all his enemies around him. He will be called Solomon. In his days I will grant peace and tranquility to Israel. He will build a temple to my name; he will be son to me and I will be father to him. I will establish the throne of his kingdom over Israel forever. Now, my son, the Lord be with you so that you will be able to build a temple to the Lord your God, as he promised you. Well, the Lord grant you wisdom and intelligence, make yourself king of Israel to observe the law of the Lord your God. Of course you will succeed, if you try to practice the statutes and decrees that the Lord has prescribed to Moses for Israel. Be strong, courage; don't be afraid and don't get down.
Isaiah 55,12-13
So you will leave with joy, you will be led in peace. The mountains and hills ahead of you will erupt in shouts of joy and all the trees in the fields will clap their hands. Instead of thorns, cypress trees will grow, instead of nettles, myrtle trees will grow; this will be to the glory of the Lord, an eternal sign that will not disappear.
