My wife and I went on a trip to an island that was known for where sea turtles would lay their eggs. In addition to seeing turtles lay their eggs, we also get to hand-release newly hatched turtles into the ocean for the first time. The survival rate of these turtles is fairly low and only the strong survive.
This is similar to new Christians. Jesus tells a parable of a farmer that scatters seed and how the seeds fall on different types of ground, some good, some no so good. He explains the parable, “When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is the one on whom seed was sown beside the road. 20 The one on whom seed was sown on the rocky places, this is the man who hears the word and immediately receives it with joy; 21 yet he has no firm root in himself, but is only temporary, and when affliction or persecution arises because of the word, immediately he falls away. 22 And the one on whom seed was sown among the thorns, this is the man who hears the word, and the worry of the world and the deceitfulness of wealth choke the word, and it becomes unfruitful. 23 And the one on whom seed was sown on the good soil, this is the man who hears the word and understands it; who indeed bears fruit and brings forth, some a hundredfold, some sixty, and some thirty” (Matthew 13:19-23, NASB).
Christians must be spiritually healthy or Satan will destroy us. Paul says to the Galatians, “I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel; which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ. But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed” (Galatians 1:6-9, NASB)! He witnessed new believers falling away by false teachings.
James tells us that we are to persevere through tribulations and that it builds our faith, “Blessed is a man who perseveres under trial; for once he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. Let no one say when he is tempted, “I am being tempted by God”; for God cannot be tempted by evil, and He Himself does not tempt anyone. But each one is tempted when he is carried away and enticed by his own lust” (James 1:12-14, NASB).
The world can lure the best of us back in to it’s sinfulness, but if we prepare ourselves for battle (spiritual battle), then we know that our strength will come from the Lord. Paul tells us just how to dress for the occasion, “Finally, be strong in the Lord and in the strength of His might. Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm. Stand firm therefore, having girded your loins with truth , and having put on the breastplate of righteousness , and having shod your feet with the preparation of the gospel of peace ; in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one. And take the helmet of salvation , and the sword of the Spirit, which is the word of God. With all prayer and petition pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints, and pray on my behalf, that utterance may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel, for which I am an ambassador in chains; that in proclaiming it I may speak boldly, as I ought to speak” (Ephesians 6:10-20.)
Trust and depend on God, fellowship with other believers and always keep God’s Word close to your heart.
