It’s because of God’s work and giving us the gift of faith enabling us to believe.What does the word "you" mean in what you quoted?
“This is the work of God, that you believe in him whom he has sent.”
The Work of God is the means by which "YOU" are to respond.
Lol, really? He gave us something to believe in? You should be ashamed of yourself how you treat God’s word. Your on the verge of breaking the third commandment by saying God said something He didn’t say.If God hadn't put forth the effort to provided something to "believe in"... Then YOU wouldn't have been able to believe.
No friend, that’s you. Your locked into your system.You're wanting to add an extra condition.
