By far the number one song request in my house is "Happy Day" by an artist named Tim Hughes. My 3 yr old son, Judah, goes absolutely wild when he hears the song....jumping...dancing...and spinning all over the living room.
The song speaks about Easter, the day we celebrate Jesus Christ's resurrection from the dead.

It was a good day for all of us, but the worst day for the Son of God. The man that was totally God-forsaken,and the God that was totally man-forsaken. He hung on that cross totally alone...the only person to ever experience ultimate rejection and isolation....and yet there was a powerful picture in His mind that awful day...

"who for the joy set before Him endured the cross, scorning it's shame..."
(Hebrews 12:2)

Happy Day (Easter) was on Jesus' mind that Good Friday. Every sick person who would receive healing because of His sacrifice were on Jesus' mind that day. All the people who would ever be set free from the bondage of sin were on Jesus' mind that day. People from every tribe, language, and nation filling heaven's banqueting table were on Jesus' mind that day. The image of a 3 year old dancing across my living room to the truth of that day, was on Jesus' mind that day and helped keep Him hanging on that old rugged cross.

Jesus made happy days possible. Happy Easter!
