I have tons of things to be thankful to God and it goes endless because every single seconds that passed there were always blessings. I can't even think of something that I can't be thankful to God knowing that they are what we call "blessings in disguise". It means they may be unpleasant at the moment but the end of it brings wonderful things for or in us.
As I sat down right here typing these words, I can't help but feeling in awe on how great our God is that He richly blessed us even if we don't feel we deserved it. I know that a lot of times I felt so stagnant in my spiritual life because of so many things that just keep me very busy but the spirit that is in us is always thirsty for God's fellowship because in the first place we are made with the need of God's fellowship. Thanks to the GRACE of God.
All this is for your benefit, so that the grace that is reaching more and more people may cause thanksgiving to overflow to the glory of God. (2 Corinthians 4:15 NIV)
