23 The Lord is my shepherd; I shall not want.
2 He maketh me to lie down in green pastures: he leadeth me beside the still waters.
3 He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake.
4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever.
Psalm 23 (KJV)

Our desire is not that others might be relieved while you are hard pressed, but that there might be equality. At the present time your plenty will supply what they need, so that in turn their plenty will supply what you need. The goal is equality, as it is written: “The one who gathered too much did not have too much, and the one who gathered too little did not have too little.” – 2 Corinthians 8:13-15
and to back up a little…
And here is my judgment about what is best for you in this matter. Last year you were the first not only to give but also to have the desire to do so. Now finish the work, so that your eager wilingness to do it may be matched by your completion of it, according to your means. For if the willingness is there, the gift is acceptable according to what one has, not according to what one does not have. – 2 Corinthians 8:10-12
The instruction here seems to be: When you see a fellow believer in need, and you have some extra to give and the willingness to do so – even if it’s not much – go ahead and give what you can.
