What Are We Offering God

I'm in Genesis now and it is awesome. I'm reading after the flood and how Noah offered God a burnt offering. (Genesis 8:20). It lead me to ask the question of: what are we offering God? Ae we even offering Him anything with exception to our prayers, asking something from Him and offering Him nothing in return?! Why can't we offer Him something without it being asked of us?! God didn't ask for the offering but Noah did it anyways. God had just done something awesome for him and his family just like God does something for us every day by waking us up!!! We take waking up for granted as if we are entitled to see another day. Smh. Let us give an offering to The Lord. It doesn't have to be monetary but something from us to Him-something that will please Him. Something from our heart. Let us show our thanks to a wonderful, long suffering, loving God, Who showed His love by sending His Son, Jesus, down to die for us.
