Never satisfied...

"Hell and Destruction are never full; so the eyes of man are never satisfied." Proverbs 27.20

Hell, the grave and human eyes have this in common: they are never satisfied. Hell and the grave are facts to those already there. But for the living, the worst are the eyes, which, if left unsupervised, will lead to hell.

Righteousness

"You shall follow what is altogether just, that you may live and inherit the land which the Lord your God is giving you." Deuteronomy 16.20

There is no other way. Whosoever wants to save their soul and inherit the Kingdom of Heaven must walk in righteousness. God is not only Righteous but also He also hates unrighteousness. Any sin, no matter how small, is a clear manifestation of unrighteousness, and they are: adultery, fornication, uncleanness, lewdness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God. (Galatians 5.19-21)

Witness

"But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.” Acts 1.8

Nobody needs to receive the Holy Spirit to be healed, delivered from evil or to be prosperous. These miracles are natural wonders of faith in Jesus.
But to an "eyewitness" of His resurrection, a new creature and to possess His character, only by receiving the baptism of the Holy Spirit can you achieve that. He is the One who maintains our salvation until death.

Infirmities

"Surely He has borne our griefs and carried our sorrows; yet we esteemed Him stricken, smitten by God, and afflicted." Isaiah 53.4

Those who know the Bible knows that the Lord Jesus has already taken all of  our infirmities and diseases. However, few are those who know how to take possession of this right. To accept it and take it without any fear or concern for medical examinations is a matter of faith that has nothing to do with the senses.

Sincere conversion

"For thus says the Lord God, the Holy One of Israel: 'In returning and rest you shall be saved; in quietness and confidence shall be your strength...'” Isaiah 30.15

Sin does not allow the heart to settle down. Only sincere conversion brings inner peace. Peace with yourself and especially with the Spirit of God. It is the tranquility that money, the glory or the power of this world cannot give. This is the force that keeps the confidence of salvation renewed.

Sincere heart

"Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water." Hebrews 10.22

The Spirit of God weighs the heart and knows when it is pure and sincere or not. Because of this, David reached mercy before God. He found true repentance to reach salvation.

Daily faith

"Now the just shall live by faith; but if anyone draws back, My soul has no pleasure in him." Hebrews 10.38

Supernatural faith is an absolute certainty that comes from above. It's more important than our daily bread, and we depend on it as much as we depend on the air we breathe. We have to breathe it in, and exercise it every second so we do not become weak. It is the energy of God, the breath of God, the power of God in us to protect our salvation.
