We cannot depend on tradition to be saved. For example, "I am from such a denomination" or "I am from such a church." We cannot depend on spiritual heroes; "I am a follower of..." or "I am a co-worker with..."
We are to produce true fruit of repentance. If we do not bear such repentance, nothing else can save us.
A Christian lady in Shanghai summed it up so nicely when she said "before the Communists came with power I was a Lutheran. Now the Communists have closed down all our churches. All I can say now is I am just a Christian."
In the final analysis this will be the only true testimony that will count.
"When they saw the courage of Peter and John and realised that they were unschooled ordinary men, they were astonished and they took note that these men had been with Jesus" (Acts 4:13).
"For you know that it was not with perishable things ... that you were redeemed from the empty way of life handed down to you from your forefathers, but with the precious blood of Christ. Through him you believe in God ... and so your faith and hope are in God" (1 Peter 1:18-21).
Produce fruit in keeping with repentance. And do not begin to say to yourselves, "We have Abraham as our father."
