The fact that you are reading is proof that you have received another gift from God – “This is the day that the Lord has made; let us rejoice and be glad in it.”
This is not a promise that the day will be easy, but a declaration of faith – this day, whatever happens, is a gift from God. He has made a new day and given you the breath in your lungs today, because He has a purpose for you today and He is always good.
There may be many things that you need the Lord’s help with today, but why not also spend time giving thanks to Him for the gift of a new day?
But in this psalm, it is more than just a physical day that they are giving thanks for. We’ve seen that the psalm is about the King’s victory. He has won the battle and He comes into the gates (v19-20). Although He was rejected, Christ is the true King and He has saved His people and it is marvellous in our eyes (v22-23).
The day you become a Christian (if you are a Christian), was the start of a new day. You were transformed and transferred from darkness to light. You are a child of the day now (1 Thessalonians 5:5). The Lord has made salvation for you and brought you into the light. So we can rejoice and be glad.
And one future day will be the final day – and the eternal day begins (Romans 13:12).
So, the call is: rejoice and be glad in the gift of a new day, the gift of salvation and the coming joy of eternal day. This day on earth may bring great challenges, but it is a gift from Him. Let’s rejoice and give thanks to Him.
