It is impossible to serve God and money. You can't do both. Jesus said this-
No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money. Matthew 6:24 ESV
I have seen many people in business who call themselves Christians actually attempt to do this, serve God and money. In fact many internet marketers appear to have a "spiritual quality" to them and they talk about being blessed by God and wanting to help people gain the level of success they have. This is very prevalent in the Internet Marketing world. In my experience when I have encountered people who claim to be Christians online, especially in Internet Marketing, and they have achieved some level of success I make a point to ask them for their help and guidance. Almost always I have been disappointed with their answers. Mostly what I get is "Have you bought all the materials available?". If you say no they don't want to help you. They believe you would be wasting their time. How I interpret that answer is they are serving mammon and so I don't want to be involved with them or their business. It is a good measuring stick for me to find out their priorities because it shows that if you have not lined their pockets with money you are not worthy of their help.
Now for sure, there is a truth that to actually run a successful and profitable business you must be committed to that business like you are committed in a marriage. However, what Jesus is talking about is a matter of priorities when He said you cannot serve both God and money. If your relationship with God is not your first priority and money and success are then no matter how much money you make you will not be fulfilled and successful. You will always be striving for more and more money and stuff because that is what first priorities do.
Eventually your first priority will put you in a position that you have to make a choice, a decision, based on your priorities. Jesus brings this up when He said you will hate the one and love the other or you will be devoted to the one and despise the other. If you are devoted to success, whatever form that takes like reaching goals of having a certain amount of money or a specific kind of car or house or material possessions, you have placed God second or third and not first. This is NOT what a Christian is called to do from the Bible. Christians are called to love God first and then your neighbor as yourself.
Is it possible to actually run a successful business and NOT serve money? Yes, it is. However, we must be very careful how we conduct ourselves in the business world. If you cannot put God above everything else Jesus said you are not worthy of Him. See Matthew 10:37,38. If you have a difficult time with making God your first priority then it is time to do so now, before you start any business venture. If you already have started you need to pray everyday for God to lead you in your business activities. You must apply Biblical principles to your business life and not worldly wisdom. The reason is that every day there will be at least one choice to make and quite possibly several choices where how you conduct yourself will ultimately depend on how you have ordered your priorities. If you want to serve God you will make the Biblical choice of loving God and putting your neighbor above yourself. If you don't you will be serving mammon or money or success.
So what I would recommend is that you sit down now and make the Biblical choice of serving God first in all things. No exceptions. No compromises. Do this and you will have no regrets. In this world of online business do not be a counterfeit Christian. Be a real Christian and God will bless you in ways you will not expect.
And quite possibly He will give you monetary blessings as well.
A man could have all the money in all the banks in all the world, and be worth nothing so far as God is concerned, if he were still living "to and for himself"!
