I know Jesus is legit because...

1. He answered my prayer to get a B in college statistics.
2. When my mom was receiving care from hospice (she was at home), a nurse said that patients who knew Jesus were peaceful towards death, but patients who did not know Him as Lord were anxious at death.
3. Before my mom died, she saw Jesus and relatives in heaven by water. She said her dad was throwing anchor in the river to pick her up. In an old hymn and I believe in the Bible it talks about the throne room of God being surrounded by a river. ("Shall We Gather by the River"; other people have testified about people dying and seeing visions of heaven.)
   
4. I have seen spiritual activity and the power of Jesus to make the spiritual activity for His glory. For example, at MD Anderson (a cancer hospital in Houston) there was an extremely pessimistic gentleman. I prayed pessimism would leave him. After fervent prayers, it did. He looked younger and his wife who was receiving treatment was the better for it.
5. My friends' little girl and I konked heads pretty hard. She looked like she might get a goose egg on her head, but she did not. We prayed.
6. My little brother fainted a long time ago. When my mom and I prayed the bump on his head would diminish, it shrank.
7. God has answered prayers for provision in money, food, medical treatment, and more for my family.

There are many more testimonies; I'll work to keep better track of them. Jesus loves you; I hope you know Him as Lord and Savior. With Him being your Savior comes a love and liberty and a Holy Spirit that is unsurpassed. Merry Christmas!
PS If you have problems with the Trinity, think of how a son can be a dad, son, and brother; and when he dies, he can be a spirit. Get the picture? =)
