The Bible is a book filled with promises. They are not empty promises, because they are the sure promises of God. He does not lie. "God who cannot lie, promised before time began" (Titus 1:2). Stand by faith upon what God promised us in Christ.
God promised to save us, when we call upon Him. "Whoever calls upon the name of the Lord shall be saved" (Joel 2:32; Romans 10:13). Whoever includes everyone who believes the promise of God. We can be saved and sure, based upon the promise of God. Call upon Him. He will save you.
God promised to completely save us. "He who has begun a good work in you will complete it until the day of Jesus Christ" (Philippians 1:6). God works in the life of every believer. He works faith, hope, and love in us as abiding gifts (1 Corinthians 13:13). What God starts, He finishes. God promises to complete this work in us.
God promised us with Yes and Amen in Christ. Through faith in Christ, all the promises are Yes to the glory of God in us. "For all the promises of God in Him are Yes and in Him Amen, to the glory of God through us" (2 Corinthians 1:20). Therefore, give glory to God for all that is promised us in Christ. God promised to work through us in Christ. What God promised us in Christ is sure, with a Yes and Amen.
