There is just no force to counteract it. So how can we fly parallel to this cliff?.
I think you're confusing the vertical component of lift and the vector quanity - lift
is a force and as such it has a magnitude and direction. Lift acts from a flow, it is always 90 degrees from the relative wind. Even if a plane is upside down in a 1g loop the aircraft is still producing lift towards the ground not opposing it. There is a big difference between not producing lift and lift not being equal to weight.
