Sharing means that eight electrons are distributed over the carbon and hydrogen atoms such that different shells are full at different times. Methane is an example of a stable covalent bond. Depending on the atoms involved, chemical reactions can result in many coinations of bonds as electrons are transferred and shared in various stable arrangements.

The Chemistry of Carbon - Purdue University
Carbon, with four valence electrons, forms covalent bonds to four neighboring carbon atoms arranged toward the corners of a tetrahedron, as shown in the figure below. Each of these sp 3 -hybridized atoms is then bound to four other carbon atoms, which form bonds to four other carbon atoms, and so on.
