Is Thanksgiving a one day a year holiday in your heart? If so, than if you will follow the three main points of First Thessalonians 5:16-18, you will have thanksgiving in your heart all year long. "Rejoice evermore. Pray without ceasing. In every thing give thanks: for this is the will of God in Christ Jesus concerning you.'
To have thanksgiving in your heart every day of the year, "rejoice evermore." Why should we rejoice? Because of what Paul wrote in Philipplans 4:4, "Rejoice in the Lord alway: and again I say, Rejoice.' Jesus and what He did for us is more than enough reason for us to rejoice.
To have thanksgiving in your heart every day of the year, "pray without ceasing." As Paul instructed the Philippian brethren, "Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God" (Philipplans 4:6). When we live for God and allow His will to control our lives than we can understand what a privilege we have in prayer.
To have thanksgiving in your heart every day of the year, "in everything give thanks." Read the New Testament and understand what God has blessed us with and that is reason to be thankful 24/7/365!
