This statement is a consequence of the principle of conservation of charge, which states that electric charge cannot be created or destroyed, only transferred from one object to another. Therefore, the sum of the currents into a junction (which represent the incoming charges) must equal the sum of the currents out of the junction (representing the outgoing charges).
