Then concluded the Savior: "So likewise shall my Heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses."
Do you think Peter would ever forget that lesson?
THE REWARD OF SACRIFICE
The Rich Young Ruler
One day Peter and others listened to a conversation between their Lord and a rich young ruler. He was a young man, rich, and, as painted by the old masters, very handsome. But with all, he had kept himself morally clean, and desired to get eternal life.[[6]] But his heart was set upon his riches; so when the Savior said, "Sell all thou hast, and distribute unto the poor, and thou shalt have treasure in heaven, and come, follow me," the young ruler went away very sorrowful.
Then Peter said, "Lo, we have left all and followed thee." As much as to say, Lord we have left everything for Thee, now what shall be our reward? Jesus said:
"There is no man who has left house, or parents, or brethren, or wife, or children, for the kingdom of God's sake, who shall not receive manifold more in this present time; and in the world to come, life everlasting."
"But," He added, "there are many who make themselves first, that shall be last; and the last first."
Humility.
This last statement must have contained for Peter, the first among the Twelve, an important lesson in Humility.
