I never denied it. As I posted a few weeks ago:
What they are refering to is often called once saved always saved. The idea behind that is once you are born again, spiritually reborn, any sin you commit is forgiven by the Blood of Christ, by grace. You do not have to work it off or you do not lose your salvation.
Even if you backslide (say fornication for example), it doesnt mean you lose your salvation, but it also does not mean you are walking with the Lord (showing proper love and respect for Him and His sacrifice) and it does not mean that you do not need to repent from your sin. Grace does not give you a license to sin. To say that it does, spits on Christ.
There is some debate about those who completely turn their back on God and Christ and deny Him after truly being born again. While this is rare, it does happen. More often, however, true believers may remain backslidden for a long period of time and still not lose their salvation. Some were never really Born Again to begin with, God knows who they are. But just because you sin doesnt automatically mean that you were never born again. We ALL WILL SIN CONSTANTLY, it is human nature.
However, IMO - and there is some scriptural evidence for it - we can blaspehme the Holy Ghost and possibly lose our salvation. But this is VERY VERY VERY hard to do to the point most Christians do not worry about it, I have no fear of it. Christ has changed my heart, my soul, washed me clean in ways I cannot express and I could no more deny Him than I could deny the Sun in the sky.
But for the vast, vast majority of Christians, we see that we are secure in Christ, that no outside forces or sin can separate us from Christ or His love. Nothing we really do, will make Him no longer love us, or make us no longer His children. Once adopted always adopted.
God knows how and when we are going to sin long before we were ever born. And Christ died for us anyway, knowing and paying for our sins on the Cross.
True born again Christians have a deep love and gratitude for the Sacrifice for all our sins and do not wish to grieve him. We know when we sin we grieve him. We are not earning contributing or anything else to our salvation, it is finished, salvation is here and it is free.
What we are doing is growing in our love and walk with Christ, WE dont do anything, He does it all. Once saved, always saved is a great security for believers because we know we WILL sin (whether we want to or not - we will) but we will not be condemned or lose our salvation for sinning against God. When God looks at us He sees the righteousness of Christ, not our sins OR good works. He only sees if we are covered in the Blood of Christ shed on the Cross.
God invites us to His mansion, rent free, debt free and gives us riches beyond belief and heals us. All we have to do is trust Him. Would you spit on your host? Would you trash his stuff? No, you would be grateful and thankful even though it will not change your situation or position or get you anything more. God will not kick you out.
