The Obedience of Christ

Why does Christ speak through the Psalmist by His Holy Spirit? Why and how did the Spirit inspire the Word of Scripture? Why was it necessary for Christ to be perfectly obedient? Did Christ ever stop being God even in the womb? Did Christ use His Godly powers in His time on earth? How did Christ entreat the favor of the Father for His children? How is doctrine dead when it lacks Love? Is anyone able to seek God with their whole heart? Why did Jesus tell the disciples that they 'know not what spirit they are of"? Who is it that robs God's glory in Christ?
