Still having a problem with lying? Don't worry, Jesus purges all His children after they get saved in order to make them perfect. The fiery trials are for our good because God uses them to make us perfect.
1 Peter 5:10
But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you.
I don't have a problem with telling the truth.
The washing away of man's sin happens well before their final judgement to determine their salvation.
The children of God don't commit sin.
They can't, as they are born of the seed of God; which can't bear evil fruit.
It is written...Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God. (1 John 3:9)
In fact, "In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother." (1 John 3:10)
It is the devil's children that commit sin.
Why do you call the devil's children the children of Jesus?
