Christians cannot be reasonably assured of eternal salvation.

Thank you for this opportunity to debate. Although I am not a Christian, I will accept this debate and argue from a Christian standpoint that Christians can be reasonably assured of eternal salvation.C1: What is reasonable?This is an automatic con vote. What is reasonable is subejctive, as someone in the comment sections already pointed out. What pro needs to do is determin an objective manner of resonable.C2: What the Bible says. John 6:38-40, "For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 “And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day.” John 10:27-28, "My sheep hear My voice, and I know them, and they follow Me; 28 and I give eternal life to them, and they shall never perish; and no one shall snatch them out of My hand." Here, Jesus promised that we will have eternal life. In John 6, he promised that anyone who beholds and believes in Him (Jesus) will have eternal life. Moreover, in John 10 Jesus promise that those who follow Me (Jesus) will be granted eternal life. Romans 8:31-39 - What then shall we say about these things? If God is for us, who can be against us? 32 Indeed, he who did not spare his own Son, but gave him up for us all—how will he not also, along with him, freely give us all things? 33 Who will bring any charge against God’s elect? It is God who justifies. 34 Who is the one who will condemn? Christ is the one who died (and more than that, he was raised), who is at the right hand of God, and who also is interceding for us. 35 Who will separate us from the love of Christ? Will trouble, or distress, or persecution, or famine, or nakedness, or danger, or sword? 36 As it is written, “ For your sake we encounter death all day long; we were considered as sheep to be slaughtered.” 37 No, in all these things we have complete victory through him who loved us! 38 For I am convinced that neither death, nor life, nor angels, nor heavenly rulers, nor things that are present, nor things to come, nor powers, 39 nor height, nor depth, nor anything else in creation will be able to separate us from the love of God in Christ Jesus our Lord. "The declaration in Romans 8:34, “Christ is the one who died,” is given in answer to the questions of verses 31-33, and in anticipation to the questions and declarations of verses 35-39. The goal of verse 34, however, is to show the absolute security of the believer. Two reasons are stated in relation to God the Son." [1] John 6:37:40 - “All that the Father gives Me shall come to Me, and the one who comes to Me I will certainly not cast out. 38 “For I have come down from heaven, not to do My own will, but the will of Him who sent Me. 39 “And this is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. 40 “For this is the will of My Father, that everyone who beholds the Son and believes in Him, may have eternal life; and I Myself will raise him up on the last day," WHAT ABOUT APOSTATES?There are no such thing as apostates in Christianity. 19 aThey went out from us, but they were not really of us; for if they had been of us, they would have remained with us; butthey went out, bso that 1it would be shown that they all are not of us. (1 John 2:19) So here, we know that if those who are apostates were really a Christian, they would have remained with us. So, we can draw the conclusion that no true Christian would leave Christianity.--->ADDRESSING MY OPPONENT'S CLAIMS<--1. God who is perfect created a perfect creatures; Lucifer, Adam & Eve.Agreed.2. Even though these created beings were perfect, still they sinned and rebelled against God.They sinned and rebelled based upon their own free will. Both still had a chance to repent.3. Once a Christian goes to heaven they a free from sin and imperfection.Accepted.4. Given the potential for eternity in heaven, it seems reasonable to assume that at some point each person will sin and rebel against God.Every person, from the moment they are born, is in constant rebellion against God. Because Jesus has given us the victory, when we are saved, we are free from the rebellion and become at peace with God the Father through Jesus His Son. Sure, Christians may backslide on occasion, but will never apostasize (see above). It is imparitive to note that the occasional backsliding does not mean that you are no longer saved. God will convict you of your sins and in some occasion will kill you out of His infinite mercy to prevent His Name from being blasphemed._______________________Sources 1. http://bible.org...;
