"Brother and Sister B, you have a work to do for yourselves which no one can do for you. You are inclined to murmur and complain. You have something to do to subdue your natural feelings. Live for God yourselves, knowing that you have not to answer for the wrongs of others. I saw, Brother B, that you would certainly be overcome by Satan, and make utter shipwreck of faith, unless you stop your faultfinding, and seek pure and undefiled religion before God. You need to be elevated in your thoughts and conversation; you need a thorough conversion. 2T 221.1"
"Holding faith, and a good conscience; which some having put away concerning faith have made shipwreck:"
Both passages discuss the concept of making 'shipwreck of faith'. EGW uses this phrase in the context of warning against faultfinding and the need for conversion, mirroring the warning in 1 Timothy.
"Life or death is before you. You should solemnly consider that you are dealing with the great God, and should ever remember that He is not a child, to be trifled with. You cannot engage in His service at will and let it alone at pleasure. Your inmost soul needs to be converted. All who, like you, my brother, have failed to grow in the grace of God, and to perfect holiness in His name, will, in these days of peril and trial, meet with great loss. Their foundation will prove to be sliding sand instead of the Rock Christ Jesus. 2T 221.2"
"And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:"
EGW's reference to a foundation of 'sliding sand instead of the Rock Christ Jesus' is a clear parallel to Jesus's teaching about building one's house on sand in Matthew 7:26.
"You move by impulse. You feel unreconciled to your brethren because you are not sent out to preach the truth. You are not fit for this trust. More than one efficient preacher would be required to follow in your wake to bind up the wounds and bruises which your harsh dealing would make. God is not pleased with you, and I fear that you will fail of everlasting life. 2T 221.3"
"But if ye bite and devour one another, take heed that ye be not consumed one of another."
The EGW passage speaks of harsh dealing that would 'make wounds and bruises', which aligns with the warning in Galatians 5:15 against biting and devouring one another.
