How Do We Sow Tears?

I would like to dissect a couple of verses in Psalms.

“Those who sow in tears shall reap in joy. He who continually goes forth weeping, bearing seed for sowing, shall doubtless come again with rejoicing, bringing his sheaves with him.”  Psalm 126:5,6 NKJV

What is the seed that will bring a harvest of joy? I believe that seed is Jesus. In Psalm 89:36, God says King David’s seed shall endure forever. Jesus was born in the linage of David and has conquered death, taken His place on the throne of heaven, and is the author and finisher of the Heavenly Kingdom that lives forever. When we sow the news of Jesus as our tears flow, He will give us joy abundantly.
