(God) turned the sea into dry land: they went through the flood on foot: there did we rejoice in Him. - Psalm 66:6
Deep calleth unto deep at the noise of Thy watersprouts: all Thy waves and Thy billows are gone over Me. - Psalm 42:7
The sea of God's wrath upon sin is now removed completely for us to pass into God's presence without worry. However, though easy for us, it meant that the waves and billows of that righteous wrath fell upon Christ. He took the full force of that wrath upon His sinless self. He endured it for us (who can imagine what He endured!). In the end, He came out triumphant! Now at that very place, we rejoice in Him!
The tempest’s awful voice was heard,
O Christ, it broke on Thee!
Thy open bosom was my ward,
It braved the storm for me.
Thy form was scarred, Thy visage marred;
Now cloudless peace for me. - Anne R. Cousin
