The liberal soul shall be made fat: and he that watereth shall be watered also himself. Proverbs 11:25 KJV
God is a giving God. Like every true father, He loves to lavish blessing upon His children. He began by giving the created cosmos to mankind. He provided and cared for His covenant people even to providing Himself a sacrifice for sin.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16 KJV
It would have been enough that He saved us but He still lavishes us with provision, healing, comfort, joy and peace.
What we have received we should share with gladness and thanksgiving for we have nothing that has not been given us by our loving, giving Father.
Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again. Luke 6:38 KJV
