A guest post from my devotional "Joy and Strength"...
"It is a good thing to give thanks unto the Lord and to sing praises unto Thy name, O most High: to show forth Thy lovingkindness in the morning, and Thy faithfulness every night." Psalm 92:1,2
"If our hearts were tuned to praise, we should see causes unnumbered, which we had never seen before, for thanking God. Thanksgiving is spoken of as a "sacrifice well pleasing unto God." It is a far higher offering than prayer. When we pay we ask for things which we want; or we tell out our sorrows. We pray, in order to bring down blessings upon ourselves; we praise, because our hearts overflow with love to God, and we must speak it out to Him. It flows out of pure love, and then the love goes back to our heats, and warms them anew, and revives and quickens them."
"Learn the lesson of thanksgiving. It is due to God, it is due to ourselves. Thanksgiving for the past makes us trustful in the present and hopeful for the future. What He has done is the pledge of what He will do." A.C.A. Hall
