Answer:
I being a Christian, will tell you that according to the Bible, Old and New Testimate it is written, "To obey is better than sacrifice" 1 Samuel 15:22. Therefore one way to thank God is to OBEY Him. Another is to Praise Him, because He is worthy to be praised, in what ever manner you desire, Sing, Dance, play an instrument because it is also written in Psalms 98. But the most simple way is to talk to God in Prayer and tell Him Thank You.
