Jesus was pretty simple with what he expected (Luke 10:27):
You shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself
This was his introduction to, possibly, his most famous parable: the Good Samaritan. According to the Jews, the Samaritans were unfit for ‘membership’ in God’s community of the faithful. They were the product of ‘mixed marriages’ between Jews and the enemy nations around Israel. The Samaritans did not hold to strict Jewish Law regarding how to worship God. But, in Jesus famous parable, it is a Samaritan (not a priest or other influential and respected Jewish leader) who exhibits ‘love for neighbor’.
So, when I say God accepts us no matter what, I mean we don’t have to have ‘all the right moves’. We may not know much about the Bible or church life. We may have a past of mistakes and failures. We may even, at present, have a few lifestyle items that won’t really shine in God’s plan.
There are a lot of things we hear about that ‘good Christians’ shouldn’t be a part of. There are a lot of things we hear about that’ good Christians’ ought to do. If we aren’t ‘there yet’ God doesn’t slam the door… we are encouraged to keep working at it. If we are ‘loving God and loving neighbor’, everything else, at least in the short term, can be worked out as we go.
