Who is God? Possibly this is one of the questions that we should have most in each of us, because when we know who God is, then we can serve Him well by recognizing each of His attributes. When we are in trials and afflictions we can recognize through all the Scriptures that God has shown His goodness and His love to deliver His people and that is why it is good that we know our God.
In chapter 25 of the book of Isaiah we find a psalm of thanksgiving for God having delivered them from their enemies and at the same time a promise from God for His people:
8 he will swallow up death forever.
The Sovereign Lord will wipe away the tears
from all faces;
he will remove his people’s disgrace
from all the earth.
The Lord has spoken.
9 In that day they will say,
“Surely this is our God;
we trusted in him, and he saved us.
This is the Lord, we trusted in him;
let us rejoice and be glad in his salvation.”
