Some things are real, others are not. Unless you are afflicted with schizophrenia any intelligent adult should be able to tell the difference. If you think you are sitting on a unicorn, you have a big problem. Get some help!!!
Otherwise, examine your life to determine which things are true and those that are not. But, what if someone told you the truth and it was difficult to believe; what then? Again, an examination is in order. Christians have faith, but they also have a brain and must use it...
2 Peter, Chapter 1
16 For we did not follow cunningly devised fables, when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty. 17 For he received from God the Father honor and glory, when the voice came to him from the Majestic Glory, “This is my beloved Son, in whom I am well pleased.” 18 We heard this voice come out of heaven when we were with him on the holy mountain.
In a court of law, one witness might be telling a lie, but it is doubtful if three people telling the same story are all liars. Consider, for a moment, if hundreds of people told the same story; should they be believed? And so we come to the following verses...
1 Corinthians, Chapter 15
1 Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand, 2 by which also you are saved, if you hold firmly the word which I preached to you—unless you believed in vain. 3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Cephas, then to the twelve. 6 Then he appeared to over five hundred brothers at once, most of whom remain until now, but some have also fallen asleep. 7 Then he appeared to James, then to all the apostles, 8 and last of all, as to the child born at the wrong time, he appeared to me also. 9 For I am the least of the apostles, who is not worthy to be called an apostle, because I persecuted the assembly of God.
What more can I say? Only this...
