When we look at the outline prayer Jesus gave, we see (especially in Luke’s narrative)that the context was one of things for which we should ask (Luke 11:9-13). We can presume that knowing Jesus’ own example, the disciples would understand that rather than a separate point of thanks in prayer, every request would be made with thanks – both for help already given in that area and in faithful expectation of God’s continued help.
As the apostle Paul wrote, we should: “… not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God” (Philippians 4:6, emphasis added). Our attitude of prayer should clearly be one of: “Giving thanks always for all things to God and the Father in the name of our Lord Jesus Christ" (Ephesians 5:20). Such an attitude of thankfulness follows the example of Jesus himself and explains why the “Lord’s Prayer” has no separate point of thanksgiving.
