Trust - I had a thought seeing the ideas going one way and then the next, saying almost exactly the same things, but from different angles.
For God so loved the world, that he gave His only Son, that who ever believes in him shall not perish but have eternal life.
Now one group says you can only obtain eternal life by believing you can reach perfection or not sinning.
The other say, we all sin, stumble from time to time, so we are sinners learning how to walk, but we often fail.
Both believe Gods promise, believing on Jesus leads to eternal life. All we know is we are a mess, and the goal is worth it.
Surely the point is we are walking and none believe sin is ok, it needs repenting of when it occurs.
The only reason one fails to walk correctly is not having communion with the Lord, with a loving heart. The pharisees were hypocrites, behaved differently than they preached. Now if you can find christians who are hypocrites, who behave differently than they preach, then you are right, they are pharisees, otherwise it is just slander, and judgementalism which the pharisee indulged in all the time. I have met good people in all strands of christian faith and evil people, it certainly is not their theology that is the problem but their hearts. Thinking on an internet discussion you can tell these apart you are sadly mistaken.
So I trust my Lord that he will deliver on his promises, I can do no other. God bless you all and may you find His love ministering to you as you go about your day.
