If a person were to lose his salvation after his believing in the Lord Jesus, what would he do with God's collateral? For instance, I have a house which rents for fifty dollars a month. A brother comes to rent it by first putting down five dollars. This is short of forty-five dollars. He says that the forty-five dollars will surely be given to me. If after a while he does not give me the forty-five dollars, what should I do? I would confiscate his five dollars. However, God cannot do this. First, the promise God has given us cannot fail. Even if God had not given us the deposit, as long as He has spoken, He will fulfill it. Even if God does not give us a pledge or a deposit, when He says that He will give us an inheritance, He will surely keep His word. Because our mind is full of legality, God gave us the Holy Spirit as the proof for us to know that God has given us the deposit. Since we have the deposit, will He not give us the inheritance?

There is a wonderful portion in the Old Testament. Genesis 24 shows us the old servant of Abraham seeking a wife for Isaac. The servant brought with him a lot of riches and precious things from Abraham's house. After he had settled with Rebecca concerning her marriage to Isaac, he gave all these things to Rebecca as engagement gifts. On the one hand, the old servant gave her all these, such as what was on her nose, fingers, head, neck, and hand, to adorn her. On the other hand, all these things were an indication to Rebecca that they were only a little token, that eventually all of Isaac's possessions would be hers.

After we are saved, due to our unbelief, we may think that God did not have the intention to save us. We wonder what would happen if salvation were merely God's toy for us, which, after a few years or a few decades, may be lost and we may become lost again. God is concerned that there may be doubts in our heart. He puts the Holy Spirit within us as the proof to assure us that He will definitely give us the inheritance. My friends, when we look at the Holy Spirit within us, we will realize that we definitely will obtain the eternal inheritance. If God is not going to give us the future inheritance, why did He give us the Holy Spirit? If God is not going to give us the future inheritance, the pledge of the Holy Spirit is meaningless. Our salvation cannot be lost, because the Holy Spirit has been given to us as the pledge. As long as this Holy Spirit is with us, we are saved. The Bible says that He will be with us until the day of redemption. Therefore, we can say assuredly and with concrete proof that we will obtain the future inheritance.
