12 See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. 13 But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. 14 We have come to share in Christ, if indeed we hold our original conviction firmly to the very end. —- Hebrews 3:12-14
When Jesus was still here on earth, He warned His disciples about being fooled by false prophets that would arise. These false prophets would claim that Jesus is coming this year or they may even claim to have seen Jesus.
23 At that time, someone might say to you, ‘Look, there is the Christ!’ Or another person might say, ‘There he is!’ But don’t believe them. 24 False Christs and false prophets will come and perform great wonders and miracles. They will try to fool even the people God has chosen, if that is possible. 25 Now I have warned you about this before it happens. — Matthew 24:23-25 NIV
We have been forewarned of the danger of taking our salvation lightly. We need to study the Word, pray and meditate on it daily. Our flesh is weak and can be easily tempted to return to its old sinful ways. It is up to us to “put on the full armor of God” every day. The armor of God is designed to fight the spiritual battle that goes on in our minds all day long, every day.
3 For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. — 2 Cor. 10:3-5 NIV
Each day, we need to encourage each other and support each other with our prayers, so that we can persevere.
36 You need to persevere so that when you have done the will of God, you will receive what he has promised. — Hebrews 10:35 NIV
