Jesus is the best evidence that God is definitely out there or with us, but you would not know unless you are connected to him. Some people are just not interested in connecting to him, at least not yet. Others do not attempt to make a good connection and get disconnected sooner or later. Some make a partial connection so that the flow of God into them is restricted and as a result, they never really get to know God well. Then we have those who make the full, firm connection, allowing God to flow into them freely, receiving grace after grace to overflowing, attaining spiritual union with God.
