Salt and light refers to the way Jesus has asked us to live as Christians in this world. We aren’t called to blend in. But to stand out and be different. Jesus’ ways weren’t the world’s ways. Wonder his ways, read the beatitudes right before this passage.

Before He went up to be with our God, He commanded us to be on mission. Go and tell others about him. Being the salt and light of the earth gives us the key in constantly being on mission for him.

Salt was a natural preservative for them in ancient times. Jesus is asking us to preserve his ways, the Word. Salt is also a seasoning. If salt loses its flavor it has no value. we are to be the salt in the lives of those around us.

In the ancient world, walls protected the cities, they were difficult to climb.  A large part of military success was overcoming the defensive walls. (Remember cannons weren’t invented until the 1700s.)  In verse 29, David is declaring and giving God the credit for military strategy and strength to overcome any wall, obstacle or defense.  God was the reason for David’s strength and success.

“ But you, O Lord, are a shield around me. You are my glory, the One who holds my head high.” - Psalm 3:3

In one of David’s darkest hours, he declared God his protector and glory.  David was fleeing from his rebellious son Absalom, who was trying to take the throne.

In the midst of panic, many, in verse 2, said God wouldn’t rescue David, likely crying out in fear.  But David stood firm and declared that God was his shield, his protector.  God was his glory.  In the midst of chaos, David stood on the mercy of God and trusted Him.  He knew that God would prevail and was still in control.  God would continue to hold him up.

“whoever dwells in the shelter of the Most High, will rest in the shadow of the Almighty.” Psalm 91:1

Psalm 91 is a beautiful picture of God’s protection when dangers come our way.  When we say ‘yes’ to Jesus, He doesn’t promise us a world of no hurt or sorrow, He promises us that we can find safety and security when we draw near to Him.

To rest in a shadow indicates a nearness.  One must walk very close to another to be in their shadow.  When we walk close to God and dwell with Him, His out-stretched arms are a shield of protection for us.  We have the assurance of His comfort and care.

Both Jesus and David pour out their soul in agony.  They feel forsaken, they are bruised, battered and weary.  But while David cries out “he has done it” as an answer to prayer, Jesus cries out “it is finished” as the plan for salvation since the beginning of time is now complete.  He has delivered His people.  One man redeemed, the other one who redeems.
