If I ever doubt my salvation, that longing unto physical sickness for the presence of God that pierces me daily would make me think otherwise. It is hard for me to wait for Heaven – granted, I'm not a terribly patient person to begin with – but on those days when nothing but His palpable presence can surfeit, the guilt of my sin overshadows my soul, and worldliness feels like a slow poison seeping into my heart, I long to see Him as He is, and to be like Him. I pray that God will keep me so broken only He can heal, so needy only He can satisfy.

My soul thirsts for God, for the living God.
When shall I come and appear before God?

O God, You are my God;
Early will I seek You;
My soul thirsts for You;
My flesh longs for You
In a dry and thirsty land
Where there is no water.
