How do I know if my surrender to God is growing properly?
Four signs of true surrender
When surrender is growing, four signs appear: loving absorption in God's name, form, pastimes and qualities; working for Him and offering the work to Him; steadiness in joy and sorrow; and fading desires.
Second, while working you think 'I am doing this for the Lord', and after finishing you offer it to Him. Third, whether happiness or sorrow, gain or loss comes, our inner joy is not affected.
