What does it mean that Christ is a hiding place from the Spirit of God?

The concept of Christ being a hiding place from the Spirit of God highlights the truth that, in our fallen state, we are vulnerable to God's scrutiny and righteous judgment. As sinners, we are unable to stand before a holy God, and thus we need a refuge. Christ is that refuge, absorbing the wrath meant for us and providing believers with peace and reconciliation with God. Through His sacrifice, we find safety from the judgment we deserve and an assurance of God's grace, which covers our sin and grants us acceptance before Him.
