Yes, struggles make you stronger.

(James 1:2-4 NIV) Consider it pure joy, my brothers, whenever you face trials of many kinds, {3} because you know that the testing of your faith develops perseverance. {4} Perseverance must finish its work so that you may be mature and complete, not lacking anything.

(1 Peter 1:6-7 NIV) In this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. {7} These have come so that your faith--of greater worth than gold, which perishes even though refined by fire--may be proved genuine and may result in praise, glory and honor when Jesus Christ is revealed.

Yes, with God all things are possible but all things are not guaranteed and all things are not likely.
