Because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in our transgressions – it is by grace you have been saved.
1 Corinthians 13:1-3
If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.
Isaiah 40:31
but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
