People forsake one another, all of the time. Just as we saw in the previous verse, good intentions, even sincerity, are often times a bad direction down the wrong path.
And when anyone is forcing you, or is leading you down the wrong path, then they are an enemy, because they are not truth.
God is truth. God never promotes false concepts.
The word for Lord, is a personal title of the Messiah, who is the God-man, namely Jesus Christ.
Since God is truth, and God is consistent, and God never changes, then He will never lead you astray, nor betray you, nor forsake you.
All of Gods blessings, and promises, are perfect, and permanent.
Once saved, always saved. Once blessed, always blessed. Once God has provided something for you, it can never be taken away.
God will never forsake those who belong to Him. And everyone who has believed in Jesus Christ, belongs to God.
When Bible doctrine has been learned, and inculcated into your soul, then God who is the living and written word, is as close as your thoughts, and resident in your soul.
