Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? Peter seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?
Just like Peter, sometimes God asks us to do something we really don't want to do. We wonder why we must do it when He isn't asking someone else to do the same. It may seem like they are getting the easy way. However, what does it matter to us what God is asking someone else to do? All we need to do is be obedient to what He is asking us to do.
