When we turned our life to Jesus, started a new life baptized in Jesus name, Jesus gave us the promise of His Spirit. (Acts 2:38-39) When we received His Spirit, the Holy Ghost, we received the joy of the Lord in our soul. The world didn't give us this joy, Jesus did, and the world can't take it away!

We have God's joy no matter how bad the circumstance, no matter how hard the trial. The joy of the Lord is our strength. When we hold on to His joy, and praise Him in our tribulation, it opens the door to great miracles. We have joy because God is good, we love Him, we have faith in Him, and trust Him. This is when God does great things.

"And when they had laid many stripes upon them, they cast them into prison, charging the jailor to keep them safely: who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks.

“And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.

“And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one's bands were loosed.

“And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled. But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here.

“Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas, And brought them out, and said, Sirs, what must I do to be saved?

“And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. And they spake unto him the word of the Lord, and to all that were in his house.

“And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway.

“And when he had brought them into his house, he set meat before them, and rejoiced, believing in God with all his house." - Acts 16:23-34 KJV
