I genuinely believe in Jesus and my life still feels hollow. What am I missing?

“O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is;”

David wrote this in a wilderness, on the run and physically far from the place he associated with worship. He does not describe a crisis of belief. He describes thirst, which is a different thing entirely: he knows exactly who he wants and cannot reach him. The psalm gives permission to be a believer and be parched at the same time, without treating that as failure.

“Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.”

On his last night with his disciples, walking out toward the garden, Jesus reaches for a vine and branch image his friends knew from the vineyards around Jerusalem. His concern is connection rather than effort. A branch does not strain to produce fruit; it stays attached. For someone doing all the right Christian things and feeling empty, that distinction is the whole question.
