Thankfulness + praise.
"Enter His gates with thanksgiving ans his courts with praise."
We have so many reasons to be thankful for! And if nothing else we can thank God for Jesus. In fact He is all we need! He gave everything for US: We have been saved, redeemed and set free! So how can we ever NOT praise Him and thank Him for all that He has done and still does? He is good and He has good in store for us. He loves us more than we can ever imagine. Trust him (through the process), turn your heart towards him and enter his presence through thankfulness. The point of your life is to point to Him and give Him Glory.
And there is always, always, always something to be thankful for.
