It is easy to be thankful for the good things. A life of rich fulfilment comes to those who are also thankful for the

setbacks. Find at least a way to be thankful for your troubles and they can become your blessings. Remember to give thanks

in all situations; because it is an opportunity for God to demonstrate His saving grace and delivering power in your

life. Give thanks with a grateful heart!!!

Your ATTITUDE to God determines your ALTITUDE in life! Align your WORD with "THE WORD" and see your WORLD

change for the BEST!
