Should we pray to the saints?

[TonyChanYT]

I wouldn't. There are no cases in the Bible where Christians pray to a saint or anyone except to God. In fact, we are instructed to pray to the Father in Jesus' name. John 16:

26 In that day you will ask in my name, and I do not say to you that I will ask the Father on your behalf; 27 for the Father himself loves you, because you have loved me and have believed that I came from God

Do you believe that Jesus came from God?

Do you believe that the Father himself loves you?

Do you believe that you can ask the Father yourself?

There is no need to pray to Mary, or some saints, or any dead people. Pray to the living God.

Philippians 4:

6 Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.
