Empowering Grace

"People are so confused about the grace of God. They think that it's simply a covering for sins. But grace is so much more. "But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ--by grace you have been saved..." Ephesians 2:4, 5 By grace I've been made alive. By grace I've been raised up. By grace I'm in Christ. * What is meant by the term replacement theology? Are Jews saved apart from Jesus Christ? * Could you hit on the topic over covenant theology vs dispensationalism? Thanks! * Can you help me understand predestination? * Why would Jesus put the woman at the well back under the law when he says "go and sin no more"?
