I know you can experience him.
Example, my wife couldn't have kids, we prayed many years for kids (actually that his will be done regarding kids for us). My father in-law had a dream. In that dream God told him to ask us that if he would give us the child of his heart, would we consider the child God's Grace (unmerited favor). We said yes. He had another dream where God told him "would we name our child Grace". No one in our family is named Grace, and no one would have ever considered naming our child Grace. Also, God stated the gender of the child by stating the name would be Grace.
5 years had passed after those dreams. My wife went to a womens conference and had a vision that she would have Grace by next years women's conference. She didn't tell anyone, but was told by someone else just after the conference that she would have a child by the following year. A few weeks later, she conceived after 12 years of marriage, and we had a girl a year later (no birth hormones). What's even stranger is that normally they have the womens conference in August. Our child was due on July 22nd. They moved the conference to July 1st, which meant that there was probably no way that she could make the conference. However, she ended up having our baby 1 month pre-mature (June 22nd) which fulfilled the prophecy that "she would have our child by next years women's conference". She went to the conference with our new healthy baby and shared her testimony. There's more to it than that, but it was a pretty amazing thing. People can say it's all chance, but I know it wasn't. The odds are extremely low of this happening all together.
He definitely shows his presence and evidence. IMO, you just have to look and be open minded.
