There is the ring of truth about the reports in the Acts of the Apostles. Peter is here stating the facts that he and a lot of the people he is preaching to, witnessed. There is no attempt at intellectualisation of the events .The events are what he knows, as is the teachings of Jesus that he is able to recall. Much that Jesus said is likely to have been missed or forgotten. The surviving uncanonical scraps are proof of this . The Truth is Jesus, the Way is Jesus and LiFe in the Love of God is Jesus. Jesus has saved us. What more do we need to know?

Jesus you know that I try to be true to you and do the will of the Father. Let me open the core of my being to the Holy Spirit and learn to hate sin and to avoid it.

The disciples in the midst of hearing a report from their friends, whose horror at the Crucifixion emptiness had caused them to run from Jerusalem, became aware that Jesus was with them. This was not a spiritual awareness as in "Didn't our hearts burn within us ?"It was their human eyes that first witnessed him and then their hands as  Jesus slowly confirmed for them the destiny that God had in store for them and for all of us. The Resurrection  is the Good News that Jesus entrusted to his fledgling Church. He ordered it to be preached. I can't think that this did not  also mean practise.

Dear Lord may your will be done on earth. May I avoid sin and become holy as you are holy.
