There are certainly many verses in the Bible that imply that. Others might say that JESUS shed HIS Divinity when HE was born in a human body, so that HE could actually suffer as any other man or woman.So, God and 'his son' aren't the same and 'the son' is subjugated to 'the father'.HE sent his SON, JESUS, to redeem mankind.
But you raise a good point as Christians have argued for centuries about the relationship between the FATHER and the SON, often violently. My position is that GOD is a Power so far beyond our comprehension that HIS relationship with HIS SON is not knowable. What I do know is that I am a sinner saved by GRACE.
