How can I be sure of the salvation of my soul?

How do you know for sure that you are saved? Consider 1 John 5: 11-13: “And the testimony is this: God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life. I have written these things to you because you know that you have eternal life, you who believe in the name of the Son of God. " Who is it that the Son has? Who believed in him and received him (John 1:12). If you have Jesus, you have life. Eternal life. Not temporary, but eternal.

God wants us to have the certainty of our salvation. We cannot live our Christian life to ask ourselves and worry every day if we are truly saved or not. That's why the Bible makes the plan of salvation so clear. Believe in Jesus Christ and you will be saved (John 3:16; Acts 16:31). Do you believe that Jesus Christ is the Savior, that he died to serve the punishment for your sins (Romans 5: 8; 2 Corinthians 5:21)? Are you trusting only in Him for salvation? If your answer is yes, you are saved! Certainty means "dispelling any doubt". By taking the Word of God to heart, you can "dispel any doubt" about the fact and reality of your eternal salvation.

Jesus himself affirms this concerning those who believed in him: “And I give them eternal life and they will never perish and nobody will kidnap them from my hand. My Father who gave them to me [His sheep] is greater than all; and no one can kidnap them from the hand of the Father "(John 10: 28-29). Again, this further emphasizes the meaning of "eternal". Eternal life is simply this: eternal. There is no one, not even you, who can take away the gift of salvation made to you by God in Christ.

Memorize these steps. We must keep the Word of God in our hearts in order not to sin against Him (Psalms 119: 11), and this includes doubt. Rejoice for what the Word of God is saying about you too: that instead of doubting, we can live with confidence! We can be sure, from the very Word of Christ, that the condition of our salvation will never be called into question. Our certainty is based on God's love for us through Jesus Christ. "To him who can preserve you from every fall and make you appear irreprehensible and joyfully before his glory, to the one God, our Savior through Jesus Christ our Lord, may glory, majesty, strength and power be before all times, now and for all centuries. Amen "(Jude 24-25).
