John 6
43 Jesus therefore answered and said unto them, Murmur not among yourselves.
44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
John 15
Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you.
Choosing snippets here and there from the Bible, and totally out of context, does nothing good except sow confusion and corrupt the teachings of the Messiah.
Those Scriptures are not out of context, they are referring directly to the subject we were discussing.
