so that this generation may be held responsible for the blood of all the prophets shed since the foundation of the world—
Luke 11:50
Although the ministry of the prophets began in earnest with men like Samuel and Elijah, God had His servants among men long before that. As far back as Abel there had been those who spoke to their fellow man the truth concerning Almighty God.
This generation here refers to those alive and active during the ministry of Christ. They had before them Emmanuel, God in the flesh. But just as the prophets had been rejected, they were rejecting Jesus.
Heavenly Father, You are full of truth and power. Your mercy and holiness are such a comfort. Hope in Christ is the apex of all good gifts from You. I will lift holy hands to You in worship every day. You are worthy of every crown, and You are wise beyond my understanding. In the Name of the Lord Jesus Christ I pray and praise You, Amen.
