Mathew 20:1-16. The spiritually minded should not be concerned with the amount of the reward, but that all will receive a reward. The kingdom of heaven is not as the world does, so why should we be concerned with the amount of the reward, when we follow Him in hope and faith that all will, whether it be early in life, late in life, or through the lake of fire.
It is not our place to say who gets what or when. For we know in our ownselves we can do nothing anyway, it is all to His glory. The greatest in the kingdom serve to minister to others, not to take glory over another.
Having a mindset of thinking we will receive more of a reward than another, seems to be carnal in nature. Truth is no matter how much I do or say does not get the reward, the reward comes through what Jesus says and does. It's no longer I who live, but He who lives in me.
Admittedly there may be differing degrees of rewards, but this is totally up to Him. To think we deserve a greater reward than another, while in this life is what He is warning us about.
Truth is, being all sinners, shouldn't we desire all to come to the knowledge. Can we take credit for anything? Should we deserve more than another? I think this is what He is addressing. Could be wrong, just my thoughts.
God bless,
