Many teach ongoing sin cannot effect your eternal security, this is totally false doctrine as Jesus shows here in
John 8:33-36 "They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?[SUP]
34 [/SUP]Jesus answered them, Verily, verily, I say unto you,
Whosoever committeth sin is the servant of sin.
[SUP]
35 [/SUP]
And the servant abideth not in the house for ever: but the Son abideth ever.
[SUP]
36 [/SUP]If the Son therefore shall make you free, ye shall be free indeed."
Also many preach you cannot be set free from the bondage and power of sin in this life, this is also a lie as Jesus also explained above.
