Sometimes there are no other words…
Recently I was in church with my family. It is the church I grew up in. Part of the service is a quiet time of prayer. It was during this time that an ovverwhelming since of greatfulness came over me and all I could say to the Lord is…
Thank you, thank you, thank you. Thank you for Your grace, for Your mercy, for Your provision, for Your protection, for Your love, for Your blessings, for never giving up on me. When there are no other words to say, tell the Lord thank you.

I do it every night and most times during the day. Words of wisdom.
