Praise means telling someone they are great, telling someone you are pleased with them and/or thanking them for doing something wonderful. A teacher might praise someone for working hard or being kind – they might say, ‘That was fantastic, I’m so pleased with what you have done, thank you for doing that for me’.
When Christians praise God they tell Him He is great and thank Him for what He has done for them; they might say: ‘Thank you for what you have done for me, thank you that you love me – I think you are fantastic.’
You might also like to talk about people deserving a medal or a trophy because of something great they have done. Explain that giving somebody a trophy or a medal is another way of praising them – it’s a way of saying ‘you’re great, that’s a wonderful thing you have done’.
