It's a sobering scene when some of the disciples following Jesus leave him. In John 6 we read:

On hearing it, many of his disciples said, "This is a hard teaching. Who can accept it?"
Aware that his disciples were grumbling about this, Jesus said to them, "Does this offend you? What if you see the Son of Man ascend to where he was before! The Spirit gives life; the flesh counts for nothing. The words I have spoken to you are spirit and they are life. Yet there are some of you who do not believe." For Jesus had known from the beginning which of them did not believe and who would betray him. 65He went on to say, "This is why I told you that no one can come to me unless the Father has enabled him." From this time many of his disciples turned back and no longer followed him.
"You do not want to leave too, do you?" Jesus asked the Twelve.
Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life. 69We believe and know that you are the Holy One of God."
Then Jesus replied, "Have I not chosen you, the Twelve? Yet one of you is a devil!"

Please note that Jesus neither chases after the ones who left, pleading with them to return, nor does He change his message to make it more palatable.

The temptation to water down the Gospel is often with us. Don't give in to it. Let God do His Work through His Word in His timing for His glory. It's not about you.
