You can only have one master.
Two divides you and leads you to be loyal to one and despise the other.
You can't serve God and money
However you can use money to serve God :)
1 Timothy 6:17-19
For the rich put your trust in the living God. Do good, enjoy what He has given you, be rich in good works, willing to share.
Do not forget to do good and share
James 1:27 true religion is visiting widows and orphans in their trouble.
Don't rob God of what is His. Bring tithes to the storehouse to put food in His house.
Satan likes to take things that are fine and twist them into becoming what we worship. God wants us to trust Him. It's not money that meets our needs, He is the Provider. Love God and use what He has given us for His glory.
