Therefore, as you received Christ Jesus the Lord, so walk in him, rooted and built up in him and established in the faith, just as you were taught, abounding in thanksgiving. – Colossians 2:6-7
If we want to have faith we need to journey with God. It is not actually the time we accepted Jesus, everything will be easy. He said that the road for disciple will be difficult. But these difficulties will be our lesson for our faith to grow.
