Voltage is known to be the difference that you can see between two points. This is the charge that you will see in between two different points.
When you say current, this is known to be the rate wherein charge will flow. It can sometimes be confusing to know the difference between rate and voltage but remember that when you say current, this is the rate by which an electric charge will flow and will reach a circuit.
In order to make things clearer for you, you should realize that voltage is known to be the cause while current is the effect of the voltage. The higher the voltage is, the stronger the current is going to be.
