A promise is always most treasured when you are down and out. When you are at your lowest, you cannot imagine happiness. That is why we need to have a mental image that gives us hope. Israel had been in exile when Jeremiah gave this promise from God. So I imagine that their mental image is the land which was promised to them in Joshua 1 – where God promises to bring them back to their homeland.
The Bible contains all His promises. Whenever we are anxious or fearful, reading His Word gives us hope and comfort. He promised us – His children – that He will never leave us nor forsake us. He promised to protect and guide us (His children). Knowing all these, we can face our future with courage. Other than that, a rainbow is painted as the background. That is because the rainbow symbolizes that God is faithful and that He will not break His promises. The colours of the rainbow remind me of His beauty.
The ram’s horn or shofar is most recognised as a musical instrument to call the people to repentance, for war, to worship and healing. But a ram’s horn is also frequently used as an instrument to carry the Oil used in anointing, praying for the sick, for consecration and as a mark of God’s spirit upon the person. The believer is to be like a ram’s horn – a call to God’s salvation – the hope in Christ but also a storage instrument of blessing to others. The purple background is a reminder of our royal priesthood.
