"Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd on the sheep, through the blood of the everlasting covenant," (Hebrews 13:20 KJV)
"Once you were like sheep who wandered away. But now you have turned to your Shepherd, the Guardian of your souls." (1 Peter 2:25 NLT)
Maybe I didn't make my point strong enough, seemingly the way I explained myself wasn't fit for some, shall we say, that might not believe that our eternal Salvation is something that can never be taken away, even if we might fall away! If that might be something you can't except, that is totally up to you; but I feel sorry for you, if you think that falling away is a deal-killer, and that is enough to cancel your Salvation.
Over the last 45 years, I might have fallen away at least half-dozen times; each and every time, there has been something that has caused me to come back; each and every time I have learned that I am always welcomed back: His arms are always wide open, ready to hug me and welcome me home!
This fallen away I am talking about is not really about turning my back on the Lord, if you think that is what I mean. The falling away that I mean is that of doing things that I should not, things that cause my fellowship with the Lord to draw distant, for a season. I am just being honest, because I know it isn't just me; there are several people I know that slipped down that slippery slope from time to time.
One thing is sure; I have never really forsaken fellowship! I might have missed a few services from time to time; but I truly believe that we must not quit trying! Even if we fall, we must aways get up and stay loyal to Christ and our fellow believers! Whatever it is that has caused up to slip away, however you think that looks like, we are always still part of the family of God, always!
I remember a Men's Meeting we had back in the 90's, out in Palo Cedro. Pastor Bill was sharing about the fact that we were all members of the Body of Christ. There was a brother who stood up, who didn't think he was good enough to be a member of the Body of Christ, saying, "If I am a member of the Body of Christ, then I must be a Hemorrhoid!"
Hopefully that doesn't offend anyone, because we all got a kick out of the way he said it. None of us are perfect! We all mess up from time to time; but we also have one great thing in common: We are saved! As long as we have been saved, we have been given eternal life in Christ! This eternal life can never be taken away, because it is secure, waiting for us in heaven...
"All praise to God, the Father of our Lord Jesus Christ. It is by his great mercy that we have been born again, because God raised Jesus Christ from the dead. Now we live with great expectation, and we have a priceless inheritance - an inheritance that is kept in heaven for you, pure and undefiled, beyond the reach of change and decay. And through your faith, God is protecting you by his power until you receive this salvation, which is ready to be revealed on the last day for all to see." (1 Peter 1:3-5 NLT)
