About a strong faith

Someone said that Christians should just forget about all that religion stuff and get on with life.

Jesus is hope for the hopeless and a helper to the foolish. To forget about Christianity? Some should forget it if they desire to have Jesus, eternity, and sin in the same moment. But to those who are frail in their way, the Lord has spoken the following: "A bruised reed he will not break, and a smoldering wick he will not snuff out, till he leads justice to victory." (Isa 42:3 and Matt. 12:20 )
Hold on to what you have until He comes. Strive and fight with the faith the Father has given you lest you lose what remains. "Wake up! Strengthen what remains and is about to die, for I have not found your deeds complete in the sight of my God." (Rev. 3:2) We are not what we were when He called us. We are not what we will be at His coming.
It is right that we should encourage each other on to our saving faith in Christ Jesus. It is wrong that we should judge before the coming day. The Apostle Paul said that he does not even judge himself. But he holds his judgment of all things for that day.
