"The Father's presence encircled Christ, and nothing befell Him but that which infinite love permitted for the blessing of the world. Here was His source of comfort, and it is for us. He who is imbued with the Spirit of Christ abides in Christ. The blow that is aimed at him falls upon the Saviour, who surrounds him with His presence. Whatever comes to him comes from Christ. He has no need to resist evil, for Christ is his defense. Nothing can touch him except by our Lord's permission, and 'all things' that are permitted 'work together for good to them that love God.' Romans 8:28" Mount of Blessings, Page 71
Frank Phillips' His Robe or Mine gives a well built explanation about justification by faith and sanctification. For further understanding (for children and adults alike), I suggest visiting their website www.justifiedwalk.com and listening to the children's story Naughty Heart Clean Heart by Susan Davis.
