I must have made the decision to accept Jesus Christ as my Savior, but I have no idea when I did this. I know I was a young child. I grew up knowing about my sin, God's great gift, Jesus Christ, and how he died on the cross that my sins could be forgiven. I memorized, and had a reasonable understanding of John 3:16.
In my world, I often heard people tell of how and when they accepted God's gift of salvation – some of these were dramatic stories – and I did not know my "when or how". So, just to be sure, I remember singing this chorus many nights in bed. "Into my heart, into my heart, come into my heart Lord Jesus. Come in today, come in to stay, come into my heart Lord Jesus". I never felt any different…
I was in junior high when my parents decided our family should change churches. Before I could become a member, I was interviewed by an elder as to my readiness to become a member of our "new church". I clearly remember my disappointment when the elder did not question me about my salvation…not really about anything.
Partly as a result of that experience, when I have interviewed potential staff members to work in Christian camps, I have tried to assume nothing – and pressed the person hard on the basics of their Christian faith.
Several times I talked with students, yes, some attending Christian colleges – who seemed to believe they would be saved through their good works. Not so. "For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God-- 9 not by works, so that no one can boast." Ephesians 2:8-9
Salvation is the free gift of God – to all who say…and believe "This is for me."
If you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. John 10:9
Be sure you have made this decision for yourself. Knowing all of the theology involved is not required. If you feel it helpful, find a Christian you can trust.
