Consider Fellowship
Heb 10:23-25 Let us hold unswervingly to the hope we profess, for he who promised is faithful. And let us consider how we may spur one another on toward love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another— and all the more as you see the Day approaching.
What is the "hope" which we profess but to enter into God's presence blameless with great joy. Thus while the world fears the coming of the Lord, the believers "wait for his Son from heaven, whom he raised from the dead— Jesus, who rescues us from the coming wrath." 1Th 1:10 To doubt the eternal security of the believer is to doubt the hope of which we profess.
Those who have been born of God continue in the faith as it is written, "They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us." 1John 2:19 Thus, "By this gospel are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain." 1Cor 15:2 Those who reject the hope never had the faith that saves to begin with. "And we are his house, if we hold on to our courage and the hope of which we boast." Heb 3:6 Otherwise we have shown ourselves to be false brethren.
The faith that saves is an application oriented faith. But unlike the Neo-Circumcision, believers don't put their faith in the applications of faith to save them, but rather put their confidence in Christ to save them. Love and good deeds are the applications of this faith. To be merely a Christian in one's theology apart from one's actions is again to show one's faith to be invalid. For "this is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother." 1John 3:10 and Jesus said, "By this all men will know that you are my disciples, if you love one another." John 13:35 "Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers." Gal 6:10
One way to practice holding fast to the hope is through regularly engaging in fellowship. And while some think that going to church on a weekly basis covers this, it says, "exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin. For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end." Heb 3:13,14 So consider how you may apply this principle of fellowship on a daily basis.
