Many have (and continue to) ask this question. Here’s what JESUS said;
Luke 10:21-22
21 In that same hour he rejoiced in the Holy Spirit and said, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will.1 22 All things have been handed over to me by my Father, and no one knows who the Son is except the Father, or who the Father is except the Son and anyone to whom the Son chooses to reveal him.
Maybe it’s not for us to know. We may think it’s because of money, pride, etc. etc. … The truth is, we don’t know!
