Jesus went to the Father so that we may do the same works he did and greater works. Saying it is in God's hands is just another way that man has enabled himself to place the blame for hardship on God. God doesn't bring hardship. God saves us from it!
but his delight is in the law of the Lord, and on his law he meditates day and night. He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers. Psalm 1:2-3 ESV
