We were talking about this in our house meeting last night
We said that once a seed is planted then it will replicate that which it has come from, and this is true of those who have the true seed of Christ, you will see the life of Christ in and through them.
Also we spoke about seedless grapes, and how they have been modified by man to suit their wants, rather than just using them in the way that God has made them. And this is like the false churches, they've changed the ways of God to suit man, over time they have modifying their teachings, eventually removing the seed which is Christ, and teaching differently to how he taught using man's understanding to try to work out the Bible and changing the word of God.
Love is the key and the core of the teachings of the gospel, and those who belong to Christ will love God as he did, and this world will mean nothing to them. God will be first in their lives and you will know them by their fruits. There are many who say they love God from their mouths but their hearts are far from him.
If we're not dying to self and doing Gods will, then we're not truly walking in the Spirit.
