T. Austin-Sparks emphasizes the incorruptible characteristics of union with God as Father, illustrating that true value in life and service is measured by intrinsic worth rather than superficial margins. He highlights that Jesus exemplified a life filled with intrinsic value, fully united with the Father through the Holy Spirit, and that this relationship was the source of His strength and the reason for His sufferings. Sparks argues that humanity was created for incorruptible life, which was lost through disobedience but restored in Christ, who provides a place for God in our hearts. The sermon challenges believers to evaluate how much of God is reflected in their lives and to ensure that their relationship with Him is one of fellowship and love, devoid of any margins of worthlessness. Ultimately, the test of our lives will be how much of God we have allowed to come through us to others.

T. Austin-Sparks emphasizes the 'plus' and 'other' of heaven in the life of Jesus, illustrating how His constant reference to heaven shaped His identity and purpose. He argues that Jesus had a heavenly background, an extra world of resources, and a different standard of living that set Him apart from the world. Sparks challenges believers to reflect on the lasting impression they leave on others, urging them to embody the incorruptible qualities of Christ. He highlights the importance of drawing from heavenly resources in times of need and maintaining a distinct Christian identity in a corrupt world. Ultimately, the sermon calls for Christians to live in a way that reflects their heavenly calling and leaves a lasting impact on those around them.
