Jesus told his disciples that “You reap where others have sown” – but it is also true that you will sow where others will reap. You may never see the fruit of your efforts, but do them anyway.
Do not be jealous for fame or attention – it may never happen in your lifetime. Or at all. Do good deeds anyway. Do what God calls you to do without attachment to outcome. If God calls you to the task, it will reach fruition in God’s time – not yours. God is meant to be glorified – not you.
We may be “standing on the shoulders of giants” – but even giants have to stand on the earth. Be humble enough to be earth – to provide a stable footing, a sure foundation, for those who build after you.
