Matthew 27:39-44
"He trusts in God; let God deliver him now, if he desires him. For he said, ‘I am the Son of God.’” (Matthew 27:43 ESV)
Jesus was being ridiculed and mocked as he hung upon the cross. Many gathered nearby to hurl insults aimed at Jesus' assertion that he was the Son of God. The unbelievers present saw opportunity to manipulate the situation for their pleasure. They sarcastically threw Jesus' identity, mission, and role in his face. Jesus never wavered in his trust for God.
When you know who you are in God you can trust Him. And the first part of that is simply knowing God Himself. With a cognitive knowledge and recognition of God and who He is to you comes the opportunity to develop an understanding for the implications that reality has on your own life. Implications that can be so profoundly impactful that they anchor your trust to God. That's the way it was for Jesus.
Once you have came to terms with the identity that flows from God to you—mission is only a heartbeat away. Just as God pours identity into you, He also puts mission before you. Mission is the great purpose for your life. It is you cause. It is God-mandated, divinely appointed. A man on mission will find a level of satisfaction and fulfillment so deeply entrenched in the peace of God that his trust for God will be unshakable.
Identity and mission work together to push you to your role. Identity answers who and whose you are. Mission answers what you should do. Role is the practical application of both—it is about being who you are and doing what you should do.
The mob didn't understand that about Jesus. His trust lay in a place beyond their mental or spiritual capacity to fathom. Yours can too.
