Assalamualaikum,
John 10:30 New International Version (NIV)
"30 I and the Father are one."
1 Corinthians 3:5-8 NKJV
"5 Who then is Paul, and who is Apollos, but ministers through whom you believed, as the Lord gave to each one? 6 I planted, Apollos watered, but God gave the increase. 7 So then neither he who plants is anything, nor he who waters, but God who gives the increase. 8 Now he who plants and he who waters ARE ONE...."
This is one more proof to prove that John 10:30 means Jesus and The Father are ONE in Purpose....the greek word used in 1 Corinthians 3:8 is ἕν(hen) which is EXACTLY the same one used in John 10:30....so basically what Paul meant is that he and Apollos were one in Purpose instead of being "literally one"...
In the NIV translation of 1 Corinthians 3:8 ἕν(Hen) is translated as "One purpose"...
"8 The one who plants and the one who waters have one purpose"
