Our Lord and Savior Jesus Christ Himself told us in clear language that all of those whom the Father has given to Him (His sheep, or the elect) will come to Him. And then He also said that whoever comes to Him He will never drive away. Jesus said that He did come not to do His own will, but His Father’s will. And He said it was His Father’s will that He should lose none of those who had been given to Him, but that they would all be raised up at the last day (John 6:37-40).
Jesus also taught us that as His sheep, we are known by Him. He said that He gives us eternal life, and we will never perish. Jesus said further that no one can snatch us out of His hand or His Father’s hand (John 10:27-30). And no one means that not even we are able to snatch ourselves out of God’s hand through any transgression of our own.
Paul taught us that there is no power in all of creation that is able to separate believers from the love of God, which is ours in Christ Jesus our Lord (Romans 8:31-39). And Paul taught us again in Romans 8 that our salvation is God’s own doing from beginning to end (Romans 8:29-30). He
also taught us clearly that the gifts and the calling of God are irrevocable
(Romans 11:29).
We also see from the Scriptures that we are not kept safe by our own power and ability to obey God, but we are kept safe by the power of God, and He is the One who will preserve us in our faith to the end (1 Peter 1:4-5, 1 Corinthians 1:8-9, 1 Thessalonians 5:23-24). Let us therefore be fully and completely confident, as Paul was when he assured us: “He who began a good work in you will perfect it until the day of Christ Jesus.” (Philippians 1:6).
God Himself began the work of salvation within us, and God Himself will carry our salvation through to its completion. Let us rejoice and give thanks to God the Father of our Lord and Savior Jesus Christ, because He has guaranteed our salvation from beginning to end, and He has left none of it in our own hands.
