Any opportunity to do good should be render immediately delay sometime may make it irrelevant again for example we see someone in need of a school fee we should try and pay immediately if we delay and such person Misses his exams even when we later pay the school fee the person make not believe in God through our giving again the person might say

" God when you actually have the power to provide this money why don't you, now I have to spend extra year well you should have just forgot about it"

But when we pay the money on time his response to God might be

" thank you Lord, I know you will provide for me, thanks for showing me this great love and mercy am writing this exam now because you are merciful to me I will forever serve you".
