Most Christian believers are worried about the wrong things. The only thing that a follower of Jesus should be worried about is his relationship with Jesus.
If you are serious about following Jesus you will absorb the words of Jesus as they are recorded in the gospels, Matthew, Mark, Luke and John. You will obey His teachings. You will repent and be baptized in water. You will stop sinning and be holy. You will be praying and seeking Jesus' guidance and approval. You will be asking Him for wisdom and understanding. You will desire to be filled with the Holy Spirit, to be led by Him.
Jesus Christ is the way, the life and the truth. Jesus is all we need, but most believers do not know Him nor follow Him. They are busy with dead religious practices and entertainment.
In the end, all that will matter is whether we knew Jesus, served Him, obeyed Him, and followed Him. We have to be bearing fruit for the kingdom of God and bringing glory to Jesus. We can only do that if we remain with Him and in His will.
How is your relationship with Jesus? Is He pleased with you?
May Jesus bless you.
