Fortunately God has made a way, and that way is through Jesus Christ, His Son whose death and resurrection were a necessary condition for our salvation, if not a sufficient condition. In other words, He died for all men, but only those that trust Christ for their salvation receive eternal life. Through faith in Christ we become children of Abraham. That is not the really special thing, what is supremely extraordinary is the relationship you have with the Living God.
In Paul’s letter to the Corinthian Church he says this:
. . . if Christ has not been raised, then our preaching is in vain and your faith is in vain. 15We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised. 1 Corinthians 15: 12-15
As a believer who has embraced Christ by faith, then we too fall under the Abrahamic Covenant, we are his children of faith, not of rebellion and disbelief. Now this is a truth, Jesus Christ is the Truth.
If you do not believe in absolute truth you are denying one of the major laws, like the Law of Gravity. You would not even think of stepping off of a ten story building, because you know you would drop like a rock.
While not a physical law, there are laws that regulate, existential and metaphysical truth; truth we must live by. One of these is called the Law of Non-contradiction. Simply put A is A and not B–or A is not non-A. In other words, something cannot be both true and false in the same way, at the same time, and in the same place.
If you say there is no truth, then the necessary question arises, “Is that true?” That is to say, you expect me to accept the statement “there is no truth,” as the truth. So your assertion defeats itself in the asking. Jesus Christ is the living Truth and God’s Word (the Bible) is His written truth to us and for us.
Jesus is the Way of the Covenant God made with Abraham and Christ Himself declared, “I am the way, the truth, and the life. No one comes to the Father, but through Me.” John 14:6
