Many believers in Christ look for assurance of salvation in all the wrong places. Some seek this assurance outside God’s word. While others look for it in the things God is doing in their lives, what they are doing for God or what opinion others have about their walk with God. The truth however remains that the easiest way to know you have assurance of salvation is to have an implicit trust on the infallible truth of God’s word.
The basic text which assures us of our salvation is 1John 5:11–13:
And this is the testimony: God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life (verse 11)
If you have Jesus the son, you have life. Not temporary life, but full, abundant, unending life. How do you know that you have the son? The answer is in John 1:12.
As many as believe in him, he gave power to become children of God.
So the assurance is in our belief! This belief is not vague, it does not leave us in doubt because it is active and evident. The simple act of giving assent to Jesus’ finished work on the cross gives us power to live a transformed glorious life made possible by his holy spirit that lives in us. It is, therefore, wrong for us to go about everyday worrying whether or not we are truly saved. Many people answer altar call again and again because of this error. Bible makes the plan of salvation so clear in Romans 10:9.
If you declare with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised him from the dead, you will be saved” (Romans 10:9).
Now, we are not talking about head knowledge or mere acknowledgement. For even the demons believe and tremble. Those who believe in him are those who have accepted his offer of holy living in place of the natural sinful nature we all received at birth. This means that you have received a new nature which is sold to righteousness. This new nature seeks to do only what Jesus approves. Even though we may fail and falter at times but our major preoccupation is to be like Jesus in all areas of life.
So, have you repented of your sins? Do you believe that Jesus died to pay the penalty for your sins and rose again from the dead (Romans 5:8; 2 Corinthians 5:21)? Do you trust, accept with a finality that you are saved and set free only by what he has done on the cross and not by your personal efforts? If your answer to these questions is “yes,” then you are saved!
Take joy in what God’s Word is saying to you: instead of doubting, we can live with confidence! We can have the assurance from Christ’s own Word that our salvation will never be in question. Our assurance of salvation is based on the perfect and complete salvation God has provided for us through Jesus Christ.
