As for the rich in this world, charge them not to be proud and arrogant and contemptuous of others, nor to set their hopes on uncertain riches, but on God, Who richly and ceaselessly provides us with everything for [our] enjoyment. 1 Timothy 6:17(AMPC)
God tells us to trust in Him because He’s the source of everything we will ever need and want. We trust in God out of the revelation that He’s able to support and sustain us in all things at all times.When we know that God is our support and sustainer then we have a healthy humble estimation of ourselves, then we do not despise others.When we trust in God who richly provides it’s easy to richly share with others what He’s provided us with.
