"Earnest money" is a deposit, it is NEVER a guarantee, and the use of the word "guarantee" is an unfortunate mistranslation used based on the biases of the translators. A deposit is valid only if conditions continue to be met. An engagement ring is a sign of earnest, signifying things to come ONLY IF conditions continue to be met.
That is a good illustration concerning the engagement ring,for they are not married yet,and not a guarantee that they will get married,seeing they could have a fallen out,and not be compatible anymore,and call off the wedding.
Or if someone puts something on credit,fails to pay along the way,the item will go back to the owner.
Someone gets probation,does not comply along the way,goes to jail.
If people in deals like that do not continue in what they started,the whole thing is called off,and null and void.
The Bible says the same thing.
Jesus said,any person having out their hand to the plough,looking back,is not fit for the kingdom of God.
Which there is only one way to interpret this.If any person starts living for God wanting to represent goodness,and abstain from worldliness,but looks back to that lifestyle admiring it,and wanting it,is not fit for the kingdom of God.
Which is why the Bible says if any person does not continue in the goodness of God,will be cut off.
When we confess our sins,and do not want sin anymore,but to represent goodness,and be Christlike,and receive the Spirit,if we do not continue in that calling,and lifestyle,then it is called off,and their salvation becomes null and void.
Rev 2:4 Nevertheless I have somewhat against thee, because thou hast left thy first love.
Rev 2:5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
Rev 3:2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.
Rev 3:3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
