In light of Q's post yesterday, I am posting for those anons who have questions in their minds. Wrtten by John MacArthur, one of the most knowledgeable and solid out there.
June 28 - The Way to Life: Simple, but Not Easy
“‘For the gate is small and the way is narrow that leads to life, and there are few who find it’” (Matthew 7:14).
God’s way of salvation is remarkably simple, but it is not easy. Nothing we can give or give up can earn us entrance into the kingdom. But if we long to hold on to forbidden things, it can keep us out of the kingdom.
Even though we can pay nothing for salvation, coming to Jesus Christ costs us everything we have. Jesus says, “Whoever does not carry his own cross and come after Me cannot be My disciple” (Luke 14:27).
The person who says yes to Christ must say no to the things of the world, because to be in Christ is to rely on His power rather than our own and to be willing to forsake our own way for His. It can cost persecution, ridicule, and tribulation.
When we identify ourselves with Jesus Christ, we declare war on the devil, and he declares war on us. The one whom we formerly served now becomes our great enemy, and the ideas and ways we once held dear now become our great temptations and pitfalls.
Along with warnings of suffering, the Lord also gives promises that our hearts will rejoice (John 16:22) and that we are to take courage because He has overcome the world (John 16:33). He promises to enable us to prevail over those times of suffering, not to escape them.
