The Scriptures use many terms to describe how we are saved through Jesus Christ and what he did on Calvary by shedding his blood for our sins and then rising again from the dead. For example, Paul declares that we are saved by hope (Romans 8:24). He writes that we are reconciled by the death of God's Son, much more, being reconciled, we shall be saved by his life (Romans 5:10). Indeed, the blood cleanses us from all sin, and the resurrection insures our justification!
The preaching of the cross is the power of God unto salvation (1 Corinthians 1:18). The gospel of Jesus Christ is also the power of God unto salvation (Romans 1:16). Yea, the gospel is the power of God unto salvation to everyone that believes in the Lord Jesus Christ! He is the grace of God freely given, whereby we are saved (by grace ye are saved - Ephesians 2:5 & 8). We have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God (Romans 5:2).
The most amazing way the Lord describes our being saved eternally is through the power of words! That is what God told Cornelius when he ordered the centurion to send for Peter, who shall tell thee words, whereby thou and all thy house shall be saved (Acts 11:14). Words whereby thou shall be saved.
What are those words? They are the words of the gospel of Jesus Christ. They are the words Cornelius had hoped to hear, knowing that God was preaching peace by Jesus Christ (Acts 10:36) through the Lord's earthly ministry and substitutionary sacrifice on the cross. Peter testifies to that. Peter also testifies to this: To him (Jesus) give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins (Acts 10:43)!
What was a head knowledge to Cornelius and his household in Acts 10:37 became a heart knowledge in Acts 10:43. The next words we read in Scripture are these: While Peter yet spake these words, the Holy Ghost fell on all them which heard the word (Acts 10:44).
Have you heard the word? Have you heard that the Son of God died for our sin and that he arose from the dead? Have you heard that he is the judge of all men? Have you heard that whosoever believes in him shall receive remission of sins at their judgment? I have. I am trusting the Lord Jesus Christ as my personal Saviour. Will you?
