Believe the record of the Bible, which is God's Word, that through Christ you have received eternal life (1 John 5:10-13). Then, by faith, walk in newness of life (2 Corinthians 5:17). Remember that you are now a living testimony of the saving power of the Lord Jesus Christ and that the new, resurrection life of Christ is being manifested in you forever, the believer.
Read and study your Bible, memorizing portions that are helpful and blessed to you. Give special attention to the promises of God to believers. Meditate on these and they will be food for your soul (1 Peter 2:2). Remember that the Word of God is the light to your pathway (Psalm 119:115) and the weapon of your warfare (Ephesians 6:17).
Pray often to God, your heavenly Father, in the name of the Lord Jesus Christ. Thank God for all things (Ephesians 5:20); praise Him for His blessings (Philippians 4:6). Ask for victory over sin and weakness (1 John 1:9). Pray for the needs of others also when praying for your own needs. A vital prayer life will keep you spiritually strong and growing.
Confess the Lord Jesus Christ as your personal Savior as a witness of your faith. (Romans 10:9-11). All who have believed in their hearts "unto salvation" will then be able to give confession of that inner reality before others. The Christian is an ambassador for Christ before a lost world (2 Corinthians 5:17-21).
Avoid temptations. The Bible tells us that they will regularly come, but we must be careful not to walk in their path (Psalm 1:1). It is also important to avoid those things that we know will hinder our Christian testimony or cause us to stumble (1 Thessalonians 5:22). When temptations arise, remember that God has promised a way of escape for those who faithfully serve and obey Him (1 Corinthians 10:13).
Witness to others about the Lord Jesus Christ (Acts 1 :8) . So many are without the Savior who else will tell them? (Romans 10:13-14). The believer's greatest joy is the privilege of telling the good news. There is nothing more important we could possibly do for others than to tell them of His power to save. Make the Gospel known to those who are lost (Romans 1:16)!
Serve the Lord with gladness (Psalm 100:2). God has a ministry for every believer (1 Corinthians 12:12-21). Join a Bible-believing, fundamental, independent, separated, non-charismatic local church. You need the pastoral care, worship, instruction and fellowship of others of like precious faith and the church needs you as well. (Hebrews 10:25). Invest your time, talents and money for eternity (Colossians 3:1-3).
Stand firmly on the Word of God (Ephesians 6:10-18). Beware of false teachers and false doctrines (2 Peter 2:1-3). Test everything by the Word of God, not by experience (Isaiah 8:20). Remember that God has promised the victory to those who honor Him and His Holy Word (1 Corinthians 15:58).
