Isaiah 50:6 I gave my back to the smiters, And my cheeks to them that plucked off the hair: I hid not my face from shame and spitting. 7 For the Lord GOD will help me; Therefore shall I not be confounded: Therefore have I set my face like a flint, And I know that I shall not be ashamed.
When Jesus was going through the pain and suffering of the cross He was not alone. God was in Christ Jesus reconciling the world unto Himself. Isaiah prophesies and says that God will help Him. That is why He could do what He could do. I set His face like a flint. He went forward. He knew that He would accomplish His purpose on the cross.
We can know that we will have success also. God will bless and use us in our service to Him. He doesn’t leave us alone. He will accomplish His purposes. We can trust Him.
