"Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship with reverence and awe, for our God is a consuming fire." - Hebrews 12:28-29
Kingdoms on this earth can be shaken. Things are not certain here. God's kingdom cannot be shaken and it is secure. No matter what may happen in this life we are guaranteed a future in Christ. That is the hope that we have to offer the people of Ethiopia. This is why we worship our God.
