I appreciate that there are parts of my last post with which you agree, but this statement of yours above is, I think, a dangerous (and unbiblical) position to take. Your salvation is God's doing, not yours. And your continued membership in His family is also His doing. He saves you and He keeps you saved (see my last post for Scripture references). You give yourself far too much power in your relationship with God - a relationship that is entirely His doing - when you make that relationship contingent upon your ability to maintain it. The clear message of Scripture is that you are, in and of yourself, utterly devoid of the capacity to save yourself, or of the desire even to want to be saved (see the first three verses of Ephesians 2). And after you're saved there remains a tension between your old, fleshly Self and the new creature in Christ you've become (Ro 7:14-24; Ga. 5:17). Left to your own devices, you would soon resort to your old manner of living, a life that is centered upon you rather than upon God. Fortunately, God takes the initiative - as He always must with us - and works in us by His Spirit to do for us what we cannot do for ourselves. All along the road we walk with God we are helpless to be who God wants us to be. Only as God supplies to us by His Spirit what we need to be "godly in Christ Jesus" can we actually be so. How, then, can our salvation be dependent upon us?
Philippians 2:13
13 for it is God who works in you both to will and to do for His good pleasure.
Jude 1:24-25
24 Now to Him who is able to keep you from stumbling, And to present you faultless Before the presence of His glory with exceeding joy,
25 To God our Savior, Who alone is wise, Be glory and majesty, Dominion and power, Both now and forever. Amen.
2 Corinthians 3:18
18 But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.
1 Thessalonians 5:23-24
23 Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.
24 He who calls you is faithful, who also will do it.
There is also another problem with the idea that you can sin sufficiently to lose your salvation: No one knows exactly where the line is between being saved and not being saved. Is it five sins, or ten, or fifty that will lose you your salvation? Who is to say? God offers no remark in His Word about how many sins makes you unsaved. Maybe only sinning once puts you out of God's family! Who knows? This uncertainty, I have noticed, produces a fearful and legalistic approach to Christian living. And many are content to have this fear of losing their salvation as an incentive to behave rightly. Of course, it is very hard to love the Person who threatens you with ejection from His family and eternal hell every time you put a foot wrong. How does one obey the first and great commandment to love God with all one's being (Matt. 22:38) if one is constantly afraid of Him? As the apostle John points out,
1 John 4:18-19
18 There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love.
19 We love Him because He first loved us.
I think if you understood better the basis of your justification and your acceptance with God, you would abandon the idea that you can do anything to reverse the salvation God has accomplished for you.
Selah.
