We should pray to God, who is 3 in one, according to the Christian doctrine of the Trinity: Father, Son and Holy Ghost. Comparing to what Muslims think, believing in the Trinity is not shirk because, for Christians, it does not go against tawhid.
If we go deeper in this subject, we’ll see that the Trinity members each have a specific “outcome” when it comes to praying:
– We should direct our prayers to the Father. Matt 6:6 and Matt 6:9; 1 Pet 1:17; Eph 3:14
– We should pray in the Son‘s (Jesus’) name. John 14:13-14
– We should pray empowered by the Holy Spirit. Eph 6:18; Romans 8:26-27
If you want to understand this topic deeper, I encourage you to go through this lesson and read these articles: Pray to God the Father in the Name of Jesus Christ and Praying to the Father in Jesus Name By Tom Brown.
Come on, Christians! Prayer is very important, so let’s pray correctly!
