Satisfaction in Christ

How do I go about becoming satisfied in my relationship with Christ? How do hear his knocking on my heart's door and let him in? My heart is crying out in agony and yet I don't feel His comfort or His voice helping me along life's journey. Rev. 3:20,22 says, " Look! Here I stand at the door and knock. If you hear me calling and open the door, I will come in, and we will share a meal as friends. Anyone who is willing to hear should listen to the Spirit and understand what the Spirit is saying to the churches." How do I go about "hearing"? How do I focus on listening? When can I share that meal as friends with my Savior? I know he can and will satisfy our spiritual hunger and thirst, but I don't know how to allow Him access to satiate me. Is it a matter of praising Him? Meditating on him day and night? Is it a conscious effort 24/7 to think on Him? My goal for this week is to follow Ps.63:1 "Oh God, you are my God; I earnestly search for you. My soul thirsts for you; my whole body longs for you in this parched and weary land where there is no water."
