"but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men."
He limited himself to the voluntary non-use of the attributes of deity. ( Walvoord )
Christ voluntarily set aside the use of some of his attributes of deity. His preincarnate glory was veiled while on earth. His non-moral attributes were not set aside or surrendered, just suspended. He did not stop being God or surrender any of His divine attributes at any time while on earth.
His Divine attributes were "concealed under a veil of flesh." (Calvin)
There is a distinct difference between emptying and concealing. If one were on a family vacation, and if one carried all his money in his wallet, one would much prefer that the wallet be concealed than emptied.
Christ's self-emptying was of His preincarnate outward glory and majesty of His deity, and that He accomplished that action by taking on the form of a servant.
Remember : Christ Did no sin ( 1 Pet. 2:22 ); Knew no sin ( 2 Cor. 5:21 ); in Him there is No sin ( 1 Jn. 3:5 ). He was the perfect , sinless Lamb of God. Christ is no less God because He is man and no less man because He is God. Christ is undiminished deity united with true humanity in one person forever ( This is known as the hypostatic union of Christ. ).
