While initially the bible verse, 'no one comes to the Father except though me' John 14:6; John 35-37 may be perplexing, daunting or even received with open doubt-- it may be also regarded as a stop sign for some; recalling the general commandment of the Lord God 'to love your neighbor as yourself,' then its significance becomes more clear.
The Christ wishes to make it known that the commandment to love isn't talk, it isn't a pretty phrase; instead it is the teaching to all growing in faith; faith is given in measures by the One Lord, by God the Creator of all. The Christ is saying that if you earnestly follow the teachings, follow the commandments, then you too will like me, ascend to paradise.
Even so many with rational, scientific minds will question, will doubt or reject this saying out of hand. Is this the only way? No. Is it the Christian way? Yes.
May the peace and grace of God's love for mankind be with you and yours. Always. Amen.
