Any saved Christian knows he's there. You can feel Jesus in your heart, and every fiber of your being, even down to the blood flowing in your veins. It's just something you can't describe in it's fullness to a non-believer. It's really cool when you first know you know Jesus. That point for me was just three years ago, even though I've been a Christian all my life.
Many even hear him, and miracles occur every day when prayers are answered or missionaries accomplish their cause. In no way is Jesus gone, the Holy Ghost is still around doing amazing things.
