The president of an ‘ex-gay’ group has said gays will go to heaven as long as they have ‘security in Christ’.

Head of Exodus International Alan Chambers recently admitted curing someone of their sexuality is impossible, drawing concerns from far right Christian organizations.

He says if anyone has given their heart to Christ, ‘salvation is inevitable’.

Chambers said: ‘The point that I’m trying to make is that we as believers can have security in Christ when we are believers.

‘I’m not saying that sin isn’t sin. I’m not saying that people should live in unrepentant sin. I’m not saying that that’s a mark of a mature believer at all.’

Several religious leaders are urging the 40-year-old, who recently admitted he still felt ‘homosexual urges, to resign as president of the US’s most prominent ex-gay organization.

Doctor A.J. Gagnon, associate professor of New Testament at Pittsburg Theological Seminary, told Christian Post Chambers is making a mockery of Exodus International.

He said: ‘The issue is Alan assures even self-professed believers who are unrepentant and self-affirming in their sin that no sinning of any magnitude or degree will keep them going to heaven.’

Chambers said even though he has surrendered his life to Jesus Christ, everyone is a victim of sin.

He told the website he is frustrated with Christians who put greater emphasis on being gay than other issues, and says all sins are equal.

He said: ‘For other people who are involved in unrepentant sin whether it’s the sin of homosexual sexual expression or gluttony or pride or heterosexual sexual expression outside of a monogamous heterosexual marriage or any other – are those people in danger of losing their salvation over those issues?

‘Would Gagnon and other people make as big a deal about that as they are with this? I don’t think so.’

Last year the organization’s former Executive Director, John Smid, came out as gay declaring, ‘One cannot repent of something that is unchangeable.’

Exodus International’s founder, Michael Bussee, also famously left the organization to begin a long term relationship with another senior office holder in the group, Gary Cooper. The couple spent the rest of Cooper’s life together before his death from AIDs in 1991.
