Value vs. Consideration

Dear experts 

Kindly let me know the difference between consideration towards supply and Value of supply. 

I see a contrast among both. 

S. 7 of CGST says Supply for consideration is Taxable. In other terms what if the supply is not for consideration? 

S. 15 r/w Valuation rules lays procedure to determine value in case supply is made for no consideration. This says Market value shall be considered to levy gst, which override the basis of Charging Provision S. 7.

Your help is highly appreciated. 

Thanks for your time.
