Some are not

Some are not
Jesus told this parable,
“Jesus told them another parable: “The kingdom of heaven is like a man who sowed good seed in his field.  
But while everyone was sleeping, his enemy came and sowed weeds among the wheat, and went away.  
When the wheat sprouted and formed heads, then the weeds also appeared. 
“The owner’s servants came to him and said, ‘Sir, didn’t you sow good seed in your field? Where then did the weeds come from?’ 
“ ‘An enemy did this,’ he replied. “The servants asked him, ‘Do you want us to go and pull them up?’ 
“ ‘No,’ he answered, ‘because while you are pulling the weeds, you may root up the wheat with them.  
Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and tie them in bundles to be burned; then gather the wheat and bring it into my barn.’” Matthew 13:24-30.
Believe it or not there are men and women in the world today who claim to be Christian but are not. There are pastors, evangelist, teachers and others in the Media within denominations, and within individual church congregations who are not Christians.
Jesus said,

“Many will say to me  on that day, 

‘Lord, Lord, did we not prophesy in your name, 

and in your name drive out demons 

and perform many miracles?’  

Then I will tell them plainly, ‘I never knew you. 

Away from me, you evildoers!’”

 Matthew 7:22,23.

 Just because someone has a pulpit in the media or in a church be it large or small. Just because someone goes to church and is active in a church congregation of denomination does not mean they are Christians.
The Church has been around for a long time it has sadly picked up a lot of baggage. There are men and women claiming to be Christians who are deceiving many. Some are taking advantage of people both spiritually and financially.
The apostle Paul tells us,

“For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires,

 they will gather around them a great number of teachers

 to say what their itching ears want to hear.  

They will turn their ears away from the truth

 and turn aside to myths.” 

2Timothy 4:3,4.

This is happening now in our day.
Equally however there are I believe far more honest, good and faithful servants of God within the twenty-first century church than there are bad people.
However the key to anyone who supports a ministry, preacher or evangelist is to constantly be on guard. To study the scriptures for yourself.
Make sure what is being preached to you is taken in context and not being twisted to forward an agenda of the one speaking.
God will one day judge those who claim to be Christians and are not. The key for now for Christians is to follow the advice of the apostle Paul who wrote,

“Do your best to present yourself to God as one approved,

 a workman who does not need to be ashamed

 and who correctly handles the word of truth.”  

2 Timothy 2:15

It is advice I would also give to non-Christians. Reading the Bible and learning what it says cannot hurt. At the very least you will learn what Christians believe and be able to decide for yourself if you believe what is being said.
Please think about it.
