In a reference to Psalm 116:10 the Apostle Paul says in 2 Corinthians 4, ""It is written: "I believed; therefore I have spoken." With that same spirit of faith we also believe and therefore speak, because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus...""
Paul was so convinced of what he saw in his mind and felt in his heart that he was able to speak it even though he was "hard pressed, crushed, persecuted, perplexed and struck down."
He was focusing on the inward not the outward. He was looking at life from the inside out.
Don't give up yet. Fix your eyes on what is unseen - the glory of God working in you - not on the troubles. For the troubles will be gone soon enough and only serve the purpose of achieving for us an eternal glory that far outweighs anything we can imagine.
